evolution, revolution,
development, evolution
“our embedded policy of continual
improvement and development ensure
the products for the future test
requirements are produced effectively
and on time”
t
oday’s stringent testing
requirements for engines,
powertrain and full
vehicles produce ever-
increasing demands on
development, certification and for
quality engineers. We understand
the customer’s needs and utilise
this cross-functional knowledge
to provide innovative test
solutions. These solutions enable
testing to be performed
accurately and reliably, from the
early stage of an engine’s
development cycle, through to
full vehicle testing and finally
the production validation and
quality assessment. Focused
market research activities along
with a structured development
process ensure that the required
innovations are brought quickly
and effectively to our customers.
Gareth Deakin, (pictured)
Business Development Director
comments that these
developments are defined by
product focus reviews with
customers and key figures
within the automotive test
market, resulting in strategic
development objectives for our
products and ensuring we react
to the market demands. To bring
these ideas to the market quickly
and effectively, we have
dramatically increased our
development investment and
we are extending research
relationships with several
universities to utilise their
immense skills in simulation
and computational techniques.
Applications
With the industry constantly
changing, solutions are being
sourced for vital contemporary
market needs such as low
emissions and fuel economy on
a global level. An excellent
example of this foresight is the
evolution of the company’s fully
integrated chassis dynamometer
and ‘Robot Driver’ for automated
testing. The robot driver has
been a huge success in
powertrain and endurance
applications worldwide. Recent
developments provide lighter
components and materials,
easier, quicker installation with
reduced cabling and enhanced
automatic set-up in the vehicle.
These features ensure the robot
driver is an effective solution in
the emission calibration and
development environments
providing high repeatability and
accuracy of drive cycle control.
Complimentary to this is the
software application that
provides ‘Real-Driver Profiling’
and a route recording/playback
system that provides powerful
‘Real-World’ simulation
capability. With the combined
control system philosophy across
our products; this functionality
also benefits our Engine and
powertrain test systems.
Other products have seen
similar benefits with a new
distributed I/O control hardware
platform; providing full test
capability before despatch and
rapid installation and
commissioning. An advanced
graphical user interface is
provided on all our systems;
modularity is designed into our
chassis dynamometers and
engine test stands for greater
flexibility and new dynos have
been developed and added.
The future
We can be sure that the pressure
on automotive powertrains and
energy sources will continue to
increase with the related need to
develop more innovative
solutions in ever shorter
timescales. Emerging
technologies will become more
prevalent with the need to test
the systems accurately and
realistically to prove their
effectiveness and to decide on
the most efficient control
strategies such as the evolving
hybrid powertrain
configurations including HEV,
PHEV, Dual mode and full
electric vehicles.
New fuel sources such as
C.N.G., Bio diesel, E85 and flex
fuel are provided for, with
enhanced fuel delivery systems
that will re-fuel test vehicles
under automated control to
ensure uninterrupted testing.
Engine and vehicle testing
accuracies are continually
improving and will interface
more extensively with simulation
programmes for “hardware-in-
the-loop” developments.
The scope is only limited by
imagination in creating real
situations under controlled
laboratory test conditions.
To remain successful,
companies in the future must be
agile and proactive to market
demands, focused on the
customer’s real challenges and
thereby establishing future
solutions. They must be able to
provide effective local, and global
support, so that the customer
can achieve their need for
reliable and effective testing.
Whatever the challenges and
obstacles we all face, you can be
sure that we are equipped and
ready to support the demands
upon our industry in the future.
IT is the Future
According to Steve Sharpe, Group
Technical Director, the future lies
in software development, both
domestically and globally.
With a responsibility for the
company’s electronic and software
products range, Steve is in charge
of research and development,
and with an impressive back-
ground in engineering (including
a degree in engineering from
Balliol College, Oxford and
recipient of the Queen’s Award
for Innovation), he has a vision
for the future that involves
moving with market forces and
supplying solutions to ever-
evolving demands.
“Fuel economy and emissions
are the key issues in all
industries at the moment,” he
comments. “This is good news
for Froude Hofmann and the
“Fuel economy and emmisions are the key issues in all
industries at the moment, this is good news for Froude
Hofmann and the way forward is to capitalise upon the
software capabilities that we already have and that we
are constantly working upon”
way forward is to capitalize upon
the software capabilities that we
already have and that we are
constantly working upon. If we
look at our newly introduced
‘Robot Driver’, it comprises the
most up-to-date and
sophisticated software yet
developed and it is my job to
ensure that this consistency of
software evolution is up to the
increasing functional
requirements of our product
range.
“Our global expansion has
opened up a huge market –
effectively, we are developing the
same products for all marketplaces
and the Far East in particular is
demanding state-of-the-art
equipment. Our task is to
provide this and we are already
working to provide unique
design solutions.”

Hybrid, Fuel Cell and Electric
propulsion
One of the key industry drivers
that is increasing exponentially is
the investment in “green” vehicle
technologies. This sees the next
stage of sophistication with regard
to hybrid powertrain solutions
requiring a more effective
integration of the powertrain
with all the vehicle’s subsystems:
ABS, traction and stability>>
control systems
Kinetic energy recovery>>
Stop/start strategies>>
Battery storage systems>>
Froude Hofmann are actively
supplying advanced 4x4 “all
independent” chassis dynamo-
meters for Hybrid and fuel cell
vehicle development. The unique
roll synchronisation control
capability of these chassis
dynamometers enables various
powertrain configurations to be
tested in accurately simulated
road and operational conditions.
Normally, with these powertrain
configurations, we have to test
“All-Wheel Drive” vehicles. The
demands placed on the chassis
dynamometer in this case are to
ensure that the synchronisation
of speed and the dynamic
adjustment of forces from front
to rear and left to right are
precise and highly responsive,
particularly important when
accelerating and braking. Under
these circumstances, the forces
have to be altered dynamically
between front and rear axles to
maintain the speed synchroni-
sation to simulate “through the
road” connection.
When this is achieved the
energy flow management system
of the vehicle will be able to
function correctly, and the test
will be representative. It is
important that the correct load
and the synchronisation is
maintained to ensure that the
correct powertrain regeneration is
observed especially as the testing
will predict key parameters such
as vehicle economy and distance
travelled etc. To obtain this level
of accuracy Froude Hofmann
have developed extremely
sophisticated control algorithms
and optimised the design of the
mechanical and electronic
sub-systems of the chassis
dynamometer to provide an
advanced system for this
demanding test application.
Hybrid Powertrain
Development of the various
configurations of Hybrid
powertrain continues to require
extensive testing to establish the
optimum configuration and
integration within the vehicle
systems. Froude Hofmann’s
individual/combined test bed
concept provides great flexibility
for testing and simulating
various configurations
Each prime mover in the
system (Electric motor and Diesel
internal combustion engine) can
be tested individually on their
respective AC dynamometer or
the two systems can be synchro-
nised together by the software
control system providing full
simulated road conditions. This
provides a unique test environ-
ment where the components can
be physically present or simulated
using software techniques
providing a full HIL system
These simulations include;
various hybrid strategy
evaluations, energy storage
simulation, battery cycler,
vehicle dynamics with various
driving styles applied.
Electric motor systems
for vehicles
The solutions for the full electric
motor vehicles require specific
test beds dedicated to high speed
synchronous AC or Permanent
Magnet motors and battery
storage devices. Our fully
integrated solutions provide the
dedicated invertor drive system,
angular rotor position
measurement, cooling systems,
instrumentation for current
sensing and battery simulation
to fully evaluate the device under
test. The battery simulator
incorporates seamlessly with our
control systems and invertor
drive systems and provides a
fully automated control and data
acquisition system.
Rocking the Real-World
Complimentary to all these test
technologies and the powertrain
solutions is the need to perform
“Real-World Simulation” testing
to ensure the product will
perform as expected and meet
all the objectives set. This is
particularly important where the
complex strategies of the latest
powertrain systems have to
accommodate varying and
interactive circumstances and
still perform and control
effectively.
Our solution is vDriver™
which can simulate the
variability associated with
particular driving styles and
routes. The system operates as a
distance based test sequencer
and enables users to reproduce
specific routes and driving styles
on their chassis, transient
engine and powertrain
dynamometers. Users can either
record routes, or select global
pre-recorded routes provided
with the vDriver™ package.
vDriver™ can then reproduces
realistic traffic and road-event
conditions in the test cell,
allowing the user to simulate
real operating conditions within
the development cycle quickly
and repeatedly. Each route
incorporates details of the road
type, speed limits, traffic lights,
stop signs and other road based
events that influence driving
styles.
These products are at the
cutting edge of testing demands
and relevant to the ongoing
developments within our
industry. Whatever these
challenges and obstacles we all
face, you can be sure that we are
equipped and ready to support
the demands upon our industry
in the future.

local yet global –
in customer services
t
erry Salter is Head of
Customer Services and his
team is unusual to say
the least. With many
years of service with Froude
Hofmann, the office-based team
employs energy, initiative,
reaction and on many occasions,
a certain amount of volatility.
Terry has been with the
company for over forty years,
working in every department
within the company except
finance – quite an amazing feat,
although the record for longevity
goes to another member of his
team, Alan Rowberry who has
managed to clock up an amazing
half century of service with the
company as man and boy.
Terry’s background as a marine
engineer has stood him in good
stead over the years, as it taught
him to work as a team, part of
a strategy that he employs as
key to his department’s success.
“Whilst working on the ships,
we had to make do with the
resources that we had available
and consequently, I learnt very
quickly that the key to success
was to how to fix things as a
team,” he comments. “And that
is precisely what we do here.
I have a fantastic team behind
me – proactive, off-the-wall
and enthusiastic and together,
we deliver real solutions.”
What Terry loves about his
job is the variety – one day
he can be dealing with small
high-speed Formula One
engines and the next, monster
marine engines. His team
deliberately comprises of people
who can contribute positively
to expanding the Froude
Hofmann network on a global
level by drawing on their own
experiences. “We set up service
infrastructures around the world
by finding a common approach,
and we strive for perfection,”
he says. And this team offers
a diverse approach. Del, sales
engineer, used to maintain
military aero engines in conflict
regions, ensuring that they
were kept in top condition for
frontline service. Dodging
enemy fire was just part of the
challenge, but it taught him
to go into tasks looking at every
eventuality. “We went into
situations that utilised all of the
resources that we had available
to us,” he comments. “And
I have learnt to apply this
philosophy to my job at Froude
Hofmann, where we are dealing
with a diverse and very
individual clientele.”
“We all have a unique
contribution to the team,”
continues Terry. “Our site
services manager, has a
background in transport: he had
the daily and unenviable job of
co-ordinating 100 British Rail
trains to run on time and on track.
His current job holds no fears or
surprises to him.”
E
x-naval engineer, Ian
is one of our technical
support engineers, he
previously worked on
UN projects installing
water pipelines and pumping
stations in the Sudan.
“We deliberately hire people
with a diverse background to
ensure we have a pool of
experienced talent,” continues
Terry. “And that’s what makes us
good. We don’t always look for
industry experience, we look for
skills and character traits that
may have applied in a completely
different way in other situations.
We don’t try to style our
operations on our industry, we
seek role models from other
industries whose methods and
performance excel.
As an example, to speed up
our machine repair turnaround,
we used the garage system as a
basis of our DYNOHAUL ‘fixed
price for fixed scope service.’” 
The whole department is
greater than the sum of its parts,
and delivers consistently
excellent support to our customer
base whether global or local.
“In the time that we have
been working with Froude
Hofmann, the company
has consistently offered
the highest levels of
professionalism and
reliability. We are currently
jointly working on two
projects, and from the
beginning, Froude

the stringent technical and
commercial requirements
to which we work,
particularly within its

products: marine
The LS-2 range has cast main
carcase sections, incorporating the
power absorption stator elements
directly into these casings provides
simplified construction and improved
reliability over the original stator
inserts.
The bedplate is a robust
fabrication designed to be clamped
at any position on its perimeter and
to protect all pipework and electrical
fittings/cabling from normal shipyard
rigours. Independently controlled
jacking systems provide a simple and
easy method of alignment.
Control of the power absorbed by
the dynamometer is by the unique
fast response characterised outlet
valve mounted directly on the casing.
This configuration provides a faster
response to load change demands
typically required for marine
propulsion system development. For
reversible dynamometers, logic
within the control system can
pre-charge the non-working
many of today’s
high-power,
low-speed heavy fuel
engines used in Marine propulsion
systems have been developed and
refined against our equipment. In
1979 with the market developing
more sophisticated drive systems
including Turbine and Nuclear fuelled
prime movers, Froude Hofmann
replaced the ever popular FA
machine and launched the innovative
LS range. These new machines
provided improved low speed control
and a number of additional features
specific for development of this new
breed of marine propulsion systems.
The Industrial and Marine Diesel
industry is well served by the FB and
LS ranges of dynamometers. The
smaller FB machines are available in
either unidirectional (AFB) or
bidirectional (BFB) versions whilst
the larger LS range comprises
machines available in unidirectional
(LS), direct reversible versions (RLS)
and double capacity (DLS) versions
covering a duty range in excess of
100,000kW
LS Dynamometers have continued
to be a key part of this ever
developing area of the marine market
and many of the original machines
are still providing reliable service to
Research and Development facilities
world wide. As part of the continuous
improvement program of this key
area of business, Froude Hofmann
continue to invest in the further
development of these machines and
control systems, this has resulted the
LS-2 range of Hydraulic
Dynamometers released this year.
All torque-transmitting
components are assembled using the
oil injection technique, eliminating
stress raising keys, keyways and
associated operating problems. This
technique also assures that
subsequent removal of components,
even after many years of service, is
simple, quick and non-destructive.

have been providing state of the art machines suitable for testing some of the
largest Diesel engines in the world.
compartment to allow smooth
transition from ahead, through zero
load, to astern for direct reversing
tests. For absolute control through
zero the LS dynamometer may be
fitted with an optional friction brake,
controlled by the dynamometer
control system. This servo control
system makes the machine inherently
suitable for automation and permits
constant speed, constant torque as
well as the conventional ‘power law’
modes of control.
For major maintenance the rotors
can be supported by means of jacks
in the bottom half casing, enabling
the coupling, bearing and water seals
to be removed from the end of the
machine and re-fitted without
dismantling the casing. This can be
carried out rapidly due to the use of
oil injection techniques considerably
reducing downtime and maintenance
costs.
Comparison of the Froude LS
dynamometers with any other
conventional type of hydraulic
dynamometer of a similar duty will
clearly show why Froude are world
leaders in the production and design
of large dynamometers for testing

closer together, blurring the
boundaries between these, has
given us greater fluidity enabling
us as a company to react to
any diversity quicker and more
effectively. With the nature
of this business where much
of the products are tailored to
the customers requirement,
every time we build a machine

presents challenges that need
to be dealt with, ensuring that
we deal with the problems as
quickly and effectively as
possible, whilst maintaining
the highest quality standards.
How We Work
“We develop our products and
operations in a systematic way.
Our product development feeds
from thorough research into our
customers’ future requirements.
Our product managers regularly
meet customers to discuss their
current needs, future needs and
any improvements they would
like in our products or services.
This allows us to move in the
direction that is required and
not waste time and resource on
projects that don’t give value to
our customers. Additionally we
aim to improve our operations
through continuous
improvement groups, and lean
events such as 5S and kaizen
activities. This allows individual
areas to own their processes and
change these rapidly if better
methods are identified or
become available”.

  • 3. 3 Froude Hofmann richard guest 2 managing director our vision we have a vision we all believe in f roude Hofmann is over 130 years old and has a long history of innovation, achievement and industry leadership. Today, at Froude Hofmann we are investing heavily to ensure our innovation keeps us at the forefront of technology and performance. That is our Mission. A Mission that is ingrained into our people, because we only employ people with the same core beliefs… people who believe in our Vision: “to provide our customers, wherever they are located in the World, with superior products that are delivered on-time and supported with world-class service” Lets look at this in a little more detail: Technical Innovation Throughout our history we have always been known for innovation and, with the backing of our owners Harris Watson group, we have significantly increased our product development programme to ensure our rate of innovation exceeds that of our competition. Our dedicated R&D team is bringing a whole series of new developments to the market that give significant operational and cost benefits to our customers. From high-speed aerospace dynamometer applications to robot-drivers that are fully integrated with emissions or durability chassis-dynamometers, our focus is in providing our customers with superior technical and operational solutions. Operational Focus When a client places an order with us, he is assured of a committed and thoroughly competent team delivering it. Our Project Management team are qualified to the internationally recognised “Prince 2” standard, and use gated project-management systems in order to ensure satisfactory project control. Our manufacturing, supply- chain and product-test teams work within a lean-systems environment to ensure a quality product is delivered on-time. Local – yet global – Service To deliver world-class service to our global customer base, we have opened four new international service centres over the past two years to supplement the three we already have. This year we will open two more to complete our world-wide footprint. “Wherever our customers need us to be, we will be…” Our spare-parts capability is being enhanced too, with higher stock-levels and a new spare-parts website to allow our clients to see what is in-stock on a real-time basis. Add to this our 16/5 technical helpline, and you have a compre- hensive service support package that surpasses most competition. Delivering Excellence Independent verification of our commitment to delivering Excellence is found in our winning the coveted “Investor in Excellence” award. This title is only awarded to companies who are found to comply with a rigorous excellence framework covering all aspects of business performance. The IiE standard is based on the European EFQM and US Baldridge Excellence models. We have this coveted standard, of course, in addition to our quality accreditations of ISO9001: 2000, ISO 14001 and TickIT. People Matter Our success can be only as good as the people we have in our business. Our philosophy is to recruit the best, and to help them develop within our team environment by providing the right training, continuous- improvement and human- resource culture. Our Customers Our customers of today are our customers of tomorrow – we never forget that for an instant. From major new projects through to spare-parts and refurbishments, we ensure our customers are fully satisfied with our performance and products.

  • 4. 5 Froude Hofmann who we are, what we do 4 where we are hull designs he established the “Froude Number” – which is the hydrodynamic equivalent of the Mach number. This is still used in ship design and many other forms of flow characterisation today. During this period he invented the hydraulic dynamometer (1877) for testing ship engines and founded the company Heenan & Froude (1881). This company moved to Worcester from Manchester and extended its product range to include equipment to test engines for ships, cars and aircraft. In parallel, Hofmann Prueftechnik evolved from the Kleinsorge Company which who we are F roude Hofmann is a well established international high-technology company dedicated to engineering excellence in the supply of testing equipment. The company has been trading for over 130 years and takes its name from the renowned English Engineer; William Froude (1810 – 1879). William Froude was educated at Oriel College, Oxford (1828) before working with Isambard Kingdom Brunel (1837) on the Great Western Railway and subsequently turning his attention to naval engineering. From his extensive research with ship W ith this impressive heritage, Froude Hofmann today provides a complete product portfolio in R&D and production environments in these markets: Aerospace>> Automotive R&D>> Automotive Production>> Industrial Turbine>> Motorsport>> Marine>> Over many years we have developed an excellent range of products within these markets. From standard dynamometers and control systems; through to fully integrated automated test systems, containerised test facilities and turnkey solutions. Aerospace & Industrial Turbine Test Products Froude Hofmann’s turbine test systems use our unique hydraulic dynamometers and Texcel VX100 control system to provide high system response and load stability. Performance covers speeds up to 30,000 RPM and power absorption up to 30 MW. Scope of supply also includes engine mounting test stands, cradles/trolleys and inertia flywheels to these segments: R&D>> Performance>> Endurance>> Quality validation>> was formed in the late 1940’s by Herr Kleinsorge, an entrepreneurial engineer previously engaged in design and development at the Junkers company, who acquired the rights to manufacture the “Junkers” smooth disc hydraulic dynamometer. Additionally Hofmann developed a range of rolling road test rigs. In 1996 the two companies came together to form Froude Hofmann – maintaining the on-going product portfolio expansion strategy and bringing R&D applications and production test skills together in one great organisation. Our products are used on the following customer systems: Aerospace turboshaft/turboprop>> Industrial turboshaft>> Turbine development systems>> Automotive Engine and Transmission Test systems Froude Hofmann offers a comprehensive range of engine dynamometers and associated control systems which provides accurate, reliable testing of engines in all applications.

  • 5. technology and innovation 6 7 Froude Hofmann evolution, revolution, development, evolution “our embedded policy of continual improvement and development ensure the products for the future test requirements are produced effectively and on time” t oday’s stringent testing requirements for engines, powertrain and full vehicles produce ever- increasing demands on development, certification and for quality engineers. We understand the customer’s needs and utilise this cross-functional knowledge to provide innovative test solutions. These solutions enable testing to be performed accurately and reliably, from the early stage of an engine’s development cycle, through to full vehicle testing and finally the production validation and quality assessment. Focused market research activities along with a structured development process ensure that the required innovations are brought quickly and effectively to our customers. Gareth Deakin, (pictured) Business Development Director comments that these developments are defined by product focus reviews with customers and key figures within the automotive test market, resulting in strategic development objectives for our products and ensuring we react to the market demands. To bring these ideas to the market quickly and effectively, we have dramatically increased our development investment and we are extending research relationships with several universities to utilise their immense skills in simulation and computational techniques. Applications With the industry constantly changing, solutions are being sourced for vital contemporary market needs such as low emissions and fuel economy on a global level. An excellent example of this foresight is the evolution of the company’s fully integrated chassis dynamometer and ‘Robot Driver’ for automated testing. The robot driver has been a huge success in powertrain and endurance applications worldwide. Recent developments provide lighter components and materials, easier, quicker installation with reduced cabling and enhanced automatic set-up in the vehicle. These features ensure the robot driver is an effective solution in the emission calibration and development environments providing high repeatability and accuracy of drive cycle control. Complimentary to this is the software application that provides ‘Real-Driver Profiling’ and a route recording/playback system that provides powerful ‘Real-World’ simulation capability. With the combined control system philosophy across our products; this functionality also benefits our Engine and powertrain test systems. Other products have seen similar benefits with a new distributed I/O control hardware platform; providing full test capability before despatch and rapid installation and commissioning. An advanced graphical user interface is provided on all our systems; modularity is designed into our chassis dynamometers and engine test stands for greater flexibility and new dynos have been developed and added. The future We can be sure that the pressure on automotive powertrains and energy sources will continue to increase with the related need to develop more innovative solutions in ever shorter timescales. Emerging technologies will become more prevalent with the need to test the systems accurately and realistically to prove their effectiveness and to decide on the most efficient control strategies such as the evolving hybrid powertrain configurations including HEV, PHEV, Dual mode and full electric vehicles. New fuel sources such as C.N.G., Bio diesel, E85 and flex fuel are provided for, with enhanced fuel delivery systems that will re-fuel test vehicles under automated control to ensure uninterrupted testing. Engine and vehicle testing accuracies are continually improving and will interface more extensively with simulation programmes for “hardware-in- the-loop” developments. The scope is only limited by imagination in creating real situations under controlled laboratory test conditions. To remain successful, companies in the future must be agile and proactive to market demands, focused on the customer’s real challenges and thereby establishing future solutions. They must be able to provide effective local, and global support, so that the customer can achieve their need for reliable and effective testing. Whatever the challenges and obstacles we all face, you can be sure that we are equipped and ready to support the demands upon our industry in the future. IT is the Future According to Steve Sharpe, Group Technical Director, the future lies in software development, both domestically and globally. With a responsibility for the company’s electronic and software products range, Steve is in charge of research and development, and with an impressive back- ground in engineering (including a degree in engineering from Balliol College, Oxford and recipient of the Queen’s Award for Innovation), he has a vision for the future that involves moving with market forces and supplying solutions to ever- evolving demands. “Fuel economy and emissions are the key issues in all industries at the moment,” he comments. “This is good news for Froude Hofmann and the “Fuel economy and emmisions are the key issues in all industries at the moment, this is good news for Froude Hofmann and the way forward is to capitalise upon the software capabilities that we already have and that we are constantly working upon” way forward is to capitalize upon the software capabilities that we already have and that we are constantly working upon. If we look at our newly introduced ‘Robot Driver’, it comprises the most up-to-date and sophisticated software yet developed and it is my job to ensure that this consistency of software evolution is up to the increasing functional requirements of our product range. “Our global expansion has opened up a huge market – effectively, we are developing the same products for all marketplaces and the Far East in particular is demanding state-of-the-art equipment. Our task is to provide this and we are already working to provide unique design solutions.” Gareth Deakin setting up the Robot Driver IT IS THE FUTURE
  • 6. 9 Froude Hofmann customer service 8 Hybrid, Fuel Cell and Electric propulsion One of the key industry drivers that is increasing exponentially is the investment in “green” vehicle technologies. This sees the next stage of sophistication with regard to hybrid powertrain solutions requiring a more effective integration of the powertrain with all the vehicle’s subsystems: ABS, traction and stability>> control systems Kinetic energy recovery>> Stop/start strategies>> Battery storage systems>> Froude Hofmann are actively supplying advanced 4x4 “all independent” chassis dynamo- meters for Hybrid and fuel cell vehicle development. The unique roll synchronisation control capability of these chassis dynamometers enables various powertrain configurations to be tested in accurately simulated road and operational conditions. Normally, with these powertrain configurations, we have to test “All-Wheel Drive” vehicles. The demands placed on the chassis dynamometer in this case are to ensure that the synchronisation of speed and the dynamic adjustment of forces from front to rear and left to right are precise and highly responsive, particularly important when accelerating and braking. Under these circumstances, the forces have to be altered dynamically between front and rear axles to maintain the speed synchroni- sation to simulate “through the road” connection. When this is achieved the energy flow management system of the vehicle will be able to function correctly, and the test will be representative. It is important that the correct load and the synchronisation is maintained to ensure that the correct powertrain regeneration is observed especially as the testing will predict key parameters such as vehicle economy and distance travelled etc. To obtain this level of accuracy Froude Hofmann have developed extremely sophisticated control algorithms and optimised the design of the mechanical and electronic sub-systems of the chassis dynamometer to provide an advanced system for this demanding test application. Hybrid Powertrain Development of the various configurations of Hybrid powertrain continues to require extensive testing to establish the optimum configuration and integration within the vehicle systems. Froude Hofmann’s individual/combined test bed concept provides great flexibility for testing and simulating various configurations Each prime mover in the system (Electric motor and Diesel internal combustion engine) can be tested individually on their respective AC dynamometer or the two systems can be synchro- nised together by the software control system providing full simulated road conditions. This provides a unique test environ- ment where the components can be physically present or simulated using software techniques providing a full HIL system These simulations include; various hybrid strategy evaluations, energy storage simulation, battery cycler, vehicle dynamics with various driving styles applied. Electric motor systems for vehicles The solutions for the full electric motor vehicles require specific test beds dedicated to high speed synchronous AC or Permanent Magnet motors and battery storage devices. Our fully integrated solutions provide the dedicated invertor drive system, angular rotor position measurement, cooling systems, instrumentation for current sensing and battery simulation to fully evaluate the device under test. The battery simulator incorporates seamlessly with our control systems and invertor drive systems and provides a fully automated control and data acquisition system. Rocking the Real-World Complimentary to all these test technologies and the powertrain solutions is the need to perform “Real-World Simulation” testing to ensure the product will perform as expected and meet all the objectives set. This is particularly important where the complex strategies of the latest powertrain systems have to accommodate varying and interactive circumstances and still perform and control effectively. Our solution is vDriver™ which can simulate the variability associated with particular driving styles and routes. The system operates as a distance based test sequencer and enables users to reproduce specific routes and driving styles on their chassis, transient engine and powertrain dynamometers. Users can either record routes, or select global pre-recorded routes provided with the vDriver™ package. vDriver™ can then reproduces realistic traffic and road-event conditions in the test cell, allowing the user to simulate real operating conditions within the development cycle quickly and repeatedly. Each route incorporates details of the road type, speed limits, traffic lights, stop signs and other road based events that influence driving styles. These products are at the cutting edge of testing demands and relevant to the ongoing developments within our industry. Whatever these challenges and obstacles we all face, you can be sure that we are equipped and ready to support the demands upon our industry in the future. rocking – the real world “We believe that this product is one of the most radical and cost-effective tools that manufacturers can employ in their pursuit of product satisfaction.”

With many years of service with Froude Hofmann, the office-based team employs energy, initiative, reaction and on many occasions, a certain amount of volatility. Terry has been with the company for over forty years, working in every department within the company except finance – quite an amazing feat, although the record for longevity goes to another member of his team, Alan Rowberry who has managed to clock up an amazing half century of service with the company as man and boy. Terry’s background as a marine engineer has stood him in good stead over the years, as it taught him to work as a team, part of a strategy that he employs as key to his department’s success. “Whilst working on the ships, we had to make do with the resources that we had available and consequently, I learnt very quickly that the key to success was to how to fix things as a team,” he comments. “And that is precisely what we do here. I have a fantastic team behind me – proactive, off-the-wall and enthusiastic and together, we deliver real solutions.” What Terry loves about his job is the variety – one day he can be dealing with small high-speed Formula One engines and the next, monster marine engines. His team deliberately comprises of people who can contribute positively to expanding the Froude Hofmann network on a global level by drawing on their own experiences. “We set up service infrastructures around the world by finding a common approach, and we strive for perfection,” he says. And this team offers a diverse approach. Del, sales engineer, used to maintain military aero engines in conflict regions, ensuring that they were kept in top condition for frontline service. Dodging enemy fire was just part of the challenge, but it taught him to go into tasks looking at every eventuality. “We went into situations that utilised all of the resources that we had available to us,” he comments. “And I have learnt to apply this philosophy to my job at Froude Hofmann, where we are dealing with a diverse and very individual clientele.” “We all have a unique contribution to the team,” continues Terry. “Our site services manager, has a background in transport: he had the daily and unenviable job of co-ordinating 100 British Rail trains to run on time and on track. His current job holds no fears or surprises to him.” E x-naval engineer, Ian is one of our technical support engineers, he previously worked on UN projects installing water pipelines and pumping stations in the Sudan. “We deliberately hire people with a diverse background to ensure we have a pool of experienced talent,” continues Terry. “And that’s what makes us good. We don’t always look for industry experience, we look for skills and character traits that may have applied in a completely different way in other situations. We don’t try to style our operations on our industry, we seek role models from other industries whose methods and performance excel. As an example, to speed up our machine repair turnaround, we used the garage system as a basis of our DYNOHAUL ‘fixed price for fixed scope service.’”  The whole department is greater than the sum of its parts, and delivers consistently excellent support to our customer base whether global or local. “In the time that we have been working with Froude Hofmann, the company has consistently offered the highest levels of professionalism and reliability.

  • 11. 19 Froude Hofmann products 18 products: marine The LS-2 range has cast main carcase sections, incorporating the power absorption stator elements directly into these casings provides simplified construction and improved reliability over the original stator inserts. The bedplate is a robust fabrication designed to be clamped at any position on its perimeter and to protect all pipework and electrical fittings/cabling from normal shipyard rigours. Independently controlled jacking systems provide a simple and easy method of alignment. Control of the power absorbed by the dynamometer is by the unique fast response characterised outlet valve mounted directly on the casing. This configuration provides a faster response to load change demands typically required for marine propulsion system development. For reversible dynamometers, logic within the control system can pre-charge the non-working many of today’s high-power, low-speed heavy fuel engines used in Marine propulsion systems have been developed and refined against our equipment. In 1979 with the market developing more sophisticated drive systems including Turbine and Nuclear fuelled prime movers, Froude Hofmann replaced the ever popular FA machine and launched the innovative LS range. These new machines provided improved low speed control and a number of additional features specific for development of this new breed of marine propulsion systems. The Industrial and Marine Diesel industry is well served by the FB and LS ranges of dynamometers. The smaller FB machines are available in either unidirectional (AFB) or bidirectional (BFB) versions whilst the larger LS range comprises machines available in unidirectional (LS), direct reversible versions (RLS) and double capacity (DLS) versions covering a duty range in excess of 100,000kW LS Dynamometers have continued to be a key part of this ever developing area of the marine market and many of the original machines are still providing reliable service to Research and Development facilities world wide. As part of the continuous improvement program of this key area of business, Froude Hofmann continue to invest in the further development of these machines and control systems, this has resulted the LS-2 range of Hydraulic Dynamometers released this year. All torque-transmitting components are assembled using the oil injection technique, eliminating stress raising keys, keyways and associated operating problems. This technique also assures that subsequent removal of components, even after many years of service, is simple, quick and non-destructive. D ynamometers, control systems and ancillary equipment are available to test a wide range of engines from the latest automotive Hybrid power units to large industrial and marine diesel engines. Applications range from Hot Test Production, End-of-Line Quality Assurance through to full Research & Development.

For absolute control through zero the LS dynamometer may be fitted with an optional friction brake, controlled by the dynamometer control system. This servo control system makes the machine inherently suitable for automation and permits constant speed, constant torque as well as the conventional ‘power law’ modes of control. For major maintenance the rotors can be supported by means of jacks in the bottom half casing, enabling the coupling, bearing and water seals to be removed from the end of the machine and re-fitted without dismantling the casing. This can be carried out rapidly due to the use of oil injection techniques considerably reducing downtime and maintenance costs. Comparison of the Froude LS dynamometers with any other conventional type of hydraulic dynamometer of a similar duty will clearly show why Froude are world leaders in the production and design of large dynamometers for testing piston, turbine and electric prime movers.

His engineering background has been invaluable in helping him to build and maintain his custom made Fiesta with two specially adapted 900CC motorbike engines which he races whenever he can. This dedication to perfection is part of John’s determination to keep the production department producing the same high quality components that he demands for his car.

Married to an Englishman, Antje has made her home in Worcestershire, adapting to the English way of life, which has been made easier with the support of her colleagues at the UK headquarters.

For over two years, David has been the company’s technical support engineer which sees him completing installations and commissioning on site. In addition, the company utilises his cultural background as in the role of customer support for the Chinese market. After graduating from Tsinghua University in China, he pursued a career in the R&D centre of Dongfeng automotive company for two years, experience which he brought with him to Froude Hofmann. David relaxes by travelling and spending time with other families, learning about their traditions and cultures, as well as participating in as many sports as time allows. Anthony enjoys drawing as a hobby. His day job is commissioning engineer which is a far throw from his previous employment with the Royal Navy and as a member of the elite Parachute Regiment. In fact, after achieving a degree in engineering, Anthony has moved around the country before settling in Worcester and bringing his mechanical and electrical engineering experience to Froude Hofmann. As well as the arts, he also enjoys spending what spare time he has with his children, entertaining them with his musical skills on the saxophone. Sports figure heavily in Dave’s social life. Froude Hofmann’s very own Marathon Man took part in this year’s London Marathon with a very respectable finish time, and has competed in numerous half marathons. In addition, he is often found hanging from cliffs with his hobby of rock climbing. This endurance stands him in good stead in his day job. Dave is often found abroad in various locations from India to the Far East as well as all over Europe in his role as Applications Engineer. With a background in mechanical engineering, Dave deals with the chassis business and having been with the company for over ten years, he is obviously still enjoying the challenge. Rachael is secretary to the Manufacturing Operations Director and the Technical Director, and has been with the company for 22 years. A far throw from her first job of working at a local horse stud, she deals with the administration within the manufacturing department, and within shop services as well as purchasing and general health and safety issues this leaves her with little spare time but she still finds time to travel the country at weekends, showing Bullmastiff dogs at shows. Rachael’s success in her hobby is reflected in the many awards she has won and includes qualification and exhibiting at Crufts.

Andy is the company’s Software Manager, co-ordinating the activities of a team of software engineers that has grown significantly during the last 12 months. In addition to working on the development of new software he also has responsibility for contract related software and providing assistance to the Technical Support Desk. Andy has been with Froude Hofmann for eight years and previously worked in the fields of accountancy and insurance but fancied a software role in a manufacturing company, for the satisfaction of seeing his own software controlling a physical product.
