M39MAE ADAMS Coursework
What needs to be Considered
By Dr. Gary Wood
Content
• Coursework load case and data
• Some things to consider
• Example: Buckling
• Some ADAMS points
Load Cases to Consider
• Understanding how load cases can
be developed is important as well
as defining the typical loads
expected for certain scenarios
• These loadings do not necessarily
cause a failure
• Nor do they mean that if passed
there will be no failure
(as this would indicate
that the element has
been over designed)
Images from
(Blundell & Harty (2004))
Load Cases to Consider
(continued)
• For an automotive application load
cases for “sign off” procedures will
have been determined
• These can be used to design the
system components to ensure that
they can sustain the loads
• Each company will have a different
set of data like the one
shown in the table
• These will be based on
previous experiences
with their vehicle
Images from
(Blundell & Harty (2004))
Load Cases to Consider (continued)
• The acceleration figures are used to give imaginary inertial force
• These values do not account for the effects of gravity
• The vehicles properties need to be considered (such as mass, CoG
height, wheel base, unspring mass etc.)
• These values can be applied to the wheel centre (be careful about
where the data may be resolved to)
Images from
(Blundell & Harty (2004))
Please Note: The loads shown in
the previous two slides are
examples, do not use for the
coursework.
How the Loads Are Applied
• The loads can be applied
to the wheel centre to
replicate the loading
condition for the
particular event
• Once the simulation is
run then the resultant
forces can be examined at
the various joints
• This is a static
analysis
Vertical Force (Fz)
Lateral Force (Fy) Longitudinal Force (Fx)
How the Loads Are Applied (continued)
• The simulation is run over
a short period to ensure
no transient are created
• The loads can be applied
such that they ramp on
over the designated time
period
• The end results is the
system in equilibrium
so that the
loads can be examined
Vertical Force (Fz)
Lateral Force (Fy) Longitudinal Force (Fx)
Some Example Simulation Results
The results show different loads and moments

Four-wheel steering provides a means to actively steer the rear wheels during turning. It improves handling and helps the model to make tighter turns.
This is relatively new technology that can be used in industries to transport the load to compact spaces and to elevate to a specific height and no requirement of cranes.
Modeling, simulation and optimization analysis of steering knuckle component ...eSAT Journals
Abstract Light weight and low fuel consumption are the two main demands for a vehicle, particularly for a race car. Steering knuckle, as one of the critical components of a race car, is the main subject in the present study. A light weight and optimized design of steering knuckle is proposed to be used for an EIMARace race car; a small high-performance formula-style car, with suitable material selection as well as valid finite element analysis and optimization studies. First part of this study involves modeling of steering knuckles and analysis of the stresses and displacement under actual load conditions. A CAD and FEA software; SolidWorks, is applied for modeling as well as for static analysis studies. Shape optimization is the second part of this study, utilizing solid Thinking software from Altair Engineering packages. The improved design obtained had achieved 45.8% reduction of mass while meeting the strength requirement. Keywords: Steering knuckle, FEA, Optimization, Race car.

Static structural analysis of suspension arm using finite element methodeSAT Journals
Abstract The function of suspension system is to absorb vibrations due to rough terrains or road disturbances and to provide stability under circumstances like accelerating, cornering, uneven road, braking, loading and unloading etc. Control arm is one of the most important part of the suspension system, as it joins the steering knuckle to the vehicle frame. Also suspension arm is responsible for up and down movement of wheels when hitting bumps. It is also designed to maximize the friction between tire contacts, patch the road surface to provide vehicle stability under any circumstances. It can be seen in many types of the suspensions like wishbone or double wishbone suspensions. Many times it is also called as A-type control arm. In this study control arm was reverse engineered. Reverse engineering refers to the process of obtaining a CAD model from an existing physical part. CAD model was prepared using CATIA v5 software and finite element analysis was done using ANSYS 14.5 software by importing the parasolid file to ANSYS. The model is subjected to loading and boundary conditions and then analyzed using the FEA techniques. The static structural analysis was done to find out the stress, deformation and safety factor of component. The model was meshed using 10-noded tetrahedral elements. Result obtained from the analysis were studied to check whether the design is safe or not. In some cases the stresses becomes more than safe limit. In that case optimization approach is carried out to increase the structural strength of the component. In this case maximum von-misses stress is 211 MPa which is below the yield strength of the material. Keywords – Suspension System, Control Arm, FEA analysis, Reverse Engineering
MASS PROPERTIES and AUTOMOTIVE DIRECTIONAL STABILITYBrian Wiegand
The quantification of automotive directional stability may be expressed through various stability metrics, but perhaps the most basic of these automotive stability metrics is the “Understeer Gradient” (Kus). The Understeer Gradient (in degrees or radians per unit gravity) appears extremely uncomplicated when viewed in its most common formulation.
This metric appears to depend only on the front and rear axle weight loads (Wf, Wr), and on the front and rear axle cornering stiffnesses (Csf, Csr). However, those last quantities vary with lateral acceleration, and the nature of that variation is dependent upon many other parameters of which some of the most basic are: Total Weight, Sprung Weight, Unsprung Weight, Forward Unsprung Weight, Rear Unsprung Weight, Total Weight LCG, Sprung Weight LCG, Total Weight VCG, Sprung Weight VCG, Track, Front Track, Rear Track, Roll Stiffness, Front Roll Stiffness, Rear Roll Stiffness, Roll Axis Height, Front Roll Center Height, and Rear Roll Center Height. Note that exactly half of these automotive directional stability parameters as listed herein are mass properties.
The purpose of this paper is to explore, through a skidpad simulation, the relative sensitivity of automotive directional stability (as quantified through the Understeer Gradient) to variation in each of the noted vehicle parameters, with special emphasis on the mass property parameters.
The simulation is constructed in a spreadsheet format from the relevant basic automotive dynamics equations; the normal and lateral loads on the tires are determined as the lateral acceleration is increased incrementally by a small amount (thereby maintaining a “quasi-static” or “steady-state” condition). The normal loads are used for the calculation of the lateral traction force potentials at each tire, with the required (centripetal) lateral traction forces apportioned accordingly. From those required (actual) lateral tire forces the corresponding tire cornering stiffnesses are determined; this determination is based upon a tire model developed through a regression analysis of tire test data.
This construction of a fairly comprehensive lateral acceleration simulation from basic automotive dynamic relationships, instead of depending upon commercial automotive software such as “CarSim” (vehicle model) and Pacjeka “Magic Formula” (tire model), constitutes a unique aspect of this paper; this return to basics hopefully provides a clearer view and understanding of the results than would be the case otherwise. Even more unique is this paper’s emphasis on, and exploration of, the role specific mass property parameters play in determining automotive directional stability.
The standard disc brake of a 4-wheeler model was done using Autodesk Mechanical Simulation through which the properties like deflection, heat flux and temperature of disc brake model were calculated. It is important to understand action force and friction force on the disc brake new material, how disc brake works more efficiently, which can help to reduce the accident that may happen at anytime.
Design, Analysis & Balancing of 5 Cylinder Engine CrankshaftIJMER
The crankshaft is a backbone of internal combustion engine. So the design & analysis is major
aspects to get high power transmission & efficiency. The selection of material is an important parameter
while designing any mechanical component. The material should be high strength & capacity to absorb
the shocks as well as fatigue. The material also have less wear tendency. The crankshaft should be high
torque transmitting capacity. So to achieve these objectives high carbon steel are used for design &
analysis purpose. This paper gives the idea about analysis as well as proper balancing of weights by using
these three materials. The modelling is done by using solid work software & then analysis by using ANSYS
software with Finite Element Analysis (FEA) method. The 5 cylinder engine gives the power stroke at 144
degree angle. By addition of counterweights & modified design these odd cylinders are balanced properly.
The Finite Element Analysis Method is used to determine stress, strains & deflection at most stressed point
which results into failure of shaft. Results obtained from analysis are used during weight optimization. The
Shaft is analyzed using static analysis. For absorbing vibrations proper damping material is used to
achieve the requirement of safe design. The optimization results into reduction of weight as well as cost

Consider the following perspective from the Just the Facts Coalition, a group comprised of counselors and other helping professionals who work with adolescent children:
Sexual orientation is not synonymous with sexual activity. Many adolescents as well as adults may identify themselves as lesbian, gay, or bisexual without having had any sexual experience with persons of the same sex. Other young people have had sexual experiences with a person of the same sex but do not consider themselves lesbian, gay, or bisexual. This is particularly relevant during adolescence because experimentation and discovery are normal and common during this developmental period. (American Psychological Association, 2013)
Straight, lesbian, gay, bisexual, transgendered, and questioning—when it comes to sexuality and sexual orientation, what influences individuals the most?
For this Discussion, review this week’s media presentation, “Perspectives: The ‘Tween’ Years,” reflecting on the factors that influence sexuality and sexual orientation during the tween years. Then, complete the post assigned to you by your Instructor.

Please choose one of the following questions, and post your resp.docxinfantsuk
Please choose one of the following questions, and post your response of a minimum of 150 words. Be sure that your comments are original, thoughtful, and well developed. This discussion will be open for the whole course, so check back frequently:
1) Most films and popular scholars would say that New Kingdom Egypt is the height of their civilization, but all the "Great Pyramids" and other culturally defining ideas are from the Old Kingdom. Which do you believe is the best period which shows the height of the Egyptians, the Old or New Kingdom Egypt? Or do you think the Middle Kingdom is the height of the Egyptians? To answer this question, choose one building, site, city, or artifact which supports your belief from either the Old, Middle, or New Kingdom. For this topic, you may use an example from the textbook, but you must find supportive information that is not mentioned in the textbook about your example from an external source (website, book, or article) to support your response. Your example could also be something not mentioned in the textbook at all. Please cite your sources for this submission.
Or
2) Discuss which of the Early Greek cultures you would like to have lived in. You may choose from the Cycladic, Minoan, Mycenaean, Athenian, or Spartan. In answering this question, please give reasons why you chose the one you did, and also give one reason for each of the other cultures as to why you would NOT want to live in that culture.
Or
3) Early archaeologists went searching for physical evidence of the myths they studied, which was due to Heinrich Schliemann's finding of Troy. Was this method of searching for mythology a good idea for searching for artifacts and physical cities? This question is asked because the stories of the myths lasted for about 2600 years before someone went looking for and found the myths of the Greeks. Why didn't someone do this before Schliemann? This idea of "myth-chasing" still goes on, so what kind of modern "myth" do people search for in our present time?

Exercise 32
Right On.
Describe what is meant by the “linear view” used with paper documents.
Exercise 40
You Spoiled It.
Motorola, Inc., fired its CFO, Paul Liska, in January for a number of reasons related to his performance as stated by Motorola. Liska has filed a suit against Motorola for the conditions of his dismissal. Motorola, accused its former CFO of destroying evidence needed in the case, and asked the Cook County Circuit court to sanction Mr. Liska for “spoiliation” of evidence in the case. When he was fired on January 29, Mr. Liska left the company with his company laptop, and when he returned his laptop on February 17, the laptop had been “wiped.” Motorola’s forensic investigators had found that a data destruction program was run on the laptop numerous times to destroy any usable data needed by Motorola to show what Mr. Liska had been working on prior to his dismissal. Mr. Liska states that he only deleted personal files.
Do you believe that all files related to the case have been destroyed?
Are there any other places that work files related to the CFO’s accounting activities would be kept?
What would have to been done to files collected from a source other than Mr. Liska’s laptop?
Would these files be acceptable in a courtroom case?
Exercise 27
Finding a Criminal.
Five customers at the Tartu Bank had complained about unauthorized monies being withdrawn from their accounts. The Bank has a business fraud team which was called together to investigate the thefts from the accounts. The team could determine the account receiving the funds, times the events occurred, the amount of the cash withdrawn from the accounts, whether a bank password had been reset, but they did not have the skills to develop additional information about the IP address used in the thefts. They could not determine the source country or region, the IPS involved, and whether the session used to withdraw the cash was from an IP used by their customer. Tell them how they can use Internet tools to further identify the cyber criminals and describe the job each tool should perform.

A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

M39MAE Coursework Considerations and support.pdfM39MAE A.docx
1. M39MAE Coursework Considerations and support.pdf
M39MAE ADAMS Coursework
What needs to be Considered
By Dr. Gary Wood
Content
• Coursework load case and data
• Some things to consider
• Example: Buckling
• Some ADAMS points
Load Cases to Consider
• Understanding how load cases can
be developed is important as well
as defining the typical loads
expected for certain scenarios
• These loadings do not necessarily
cause a failure
2. • Nor do they mean that if passed
there will be no failure
(as this would indicate
that the element has
been over designed)
Images from
(Blundell & Harty (2004))
Load Cases to Consider
(continued)
• For an automotive application load
cases for “sign off” procedures will
have been determined
• These can be used to design the
system components to ensure that
they can sustain the loads
• Each company will have a different
set of data like the one
shown in the table
• These will be based on
previous experiences
with their vehicle
Images from
(Blundell & Harty (2004))
Load Cases to Consider (continued)
3. • The acceleration figures are used to give imaginary inertial
force
• These values do not account for the effects of gravity
• The vehicles properties need to be considered (such as mass,
CoG
height, wheel base, unspring mass etc.)
• These values can be applied to the wheel centre (be careful
about
where the data may be resolved to)
Images from
(Blundell & Harty (2004))
Please Note: The loads shown in
the previous two slides are
examples, do not use for the
coursework.
How the Loads Are Applied
• The loads can be applied
to the wheel centre to
replicate the loading
condition for the
particular event
• Once the simulation is
run then the resultant
4. forces can be examined at
the various joints
• This is a static
analysis
Vertical Force (Fz)
Lateral Force (Fy) Longitudinal Force (Fx)
How the Loads Are Applied (continued)
• The simulation is run over
a short period to ensure
no transient are created
• The loads can be applied
such that they ramp on
over the designated time
period
• The end results is the
system in equilibrium
so that the
loads can be examined
Vertical Force (Fz)
Lateral Force (Fy) Longitudinal Force (Fx)
Some Example Simulation Results
The results show different loads and moments
5. Suspension Data
• Below is the suspension
geometry that will be used for
the coursework
• Note there is data for the bump
stops
Front Suspension Main Parts (passenger side)
The suspension spring
stiffness is 132 N/mm
Vehicle Mass (m) 1300 kg
CG Height (CG) 480 mm
Weight Distribution (WD) 53% Front
Wheelbase (W) 2550 mm
Track (t) 1700 mm
SLR (SLR) 300 mm
Unsprung (m_u) 45 kg
Acceleration due to gravity (g) 9.81 m/s2
Vehicle Data for the CW
• The overall vehicle parameters are shown in the table
below
6. • These are used to determine the static values used
for the analysis
• After this the loads are applied to the suspension for
the various scenarios

Please note that only the front right wheel needs to be modelled
in terms of loads, the rest are
given for information
CW Analysis
• All of the scenarios in the previous slides need to be
evaluated
• These will allow for the general loading condition that the
tie rod will be subjected to
• The design of the tie rod needs to be such that it can
support these loads
• Above these values however a failure needs to be
introduced such that it protects the other components of
the suspension
9. • The solution needs to be in a form such as a “mechanical
fuse”, this is down to the groups to consider and design
Aim of the Coursework
• The main idea of the second coursework is to
develop a design that can be proven to fail in a
specific way
• Remember the aim of the design is to be a
sacrificial element to protect more vital
components (such as the wheel knuckle and
steering rack)
• There are a number of areas that need to be
considered to accomplish this
Aim of the Coursework
(continued)
• There have been some ideas highlighted that
can and should be considered but there are a
wide variety of alternatives that can be used
• The design needs to consider what might
happen during its use and how these can be
mitigated through the design
• Further consideration needs to be given for
the application such as cost and weight
10. Buckling – One Area to Consider
“Buckling can be defined as the sudden large
deformation of structure due to a slight increase
of an existing load under which the structure
had exhibited little, if any, deformation before
the load was increased”
From Assakkaf (2013)
Buckling
• Some notes and examples on Buckling have
been added onto Moodle
• These can be used to form a base for the
investigation
• The loads that the tie rod will experience can
be determined from ADAMS
Buckling – (continued)
• A simple example would be a hinge-hinge
joint, free to rotate at each end
11. • The critical buckling load can be given by:
Images from (Clifford et al 2010)

Buckling – (continued)
• The areas to consider here are E (Young's
modulus) and I (second moment of area)
• This means material and shape considerations

12. Buckling – (continued)
• The areas to consider here are E (Young's
modulus) and I (second moment of area)
• This means material and shape considerations
Images from (Clifford et al 2010)
Buckling – (continued)
• Potential for other more interesting designs
could be an eccentrically loaded strut
• More complicated but closer to the actual
design needed……. you decide
Images from (Clifford et al 2010)
Images from (Pascarella & Vogler 2008)
Consider the Design
• You should consider what has been designed before
• Learn from the ideas and think about why they have
been designed in that manner
• Build up your own hypothesis and use these to build
your design
13. • Remember to consider the
application and the impact
that this can have on the
design considerations
Aston Martin Control Arm
• Here it can be clearly seen that there is a
distinct “kink” in the control arm
• What do you think
this is?
• Could a similar
principle help your
design?
Images from (Pascarella & Vogler 2008)
Control of the Failure
• The failure mode is very important
• You do not want a brittle failure
• This will cause the vehicle to have an
uncontrollable response to the failure
Images from (IH8MUD 2013)
Control of the Failure
14. • The failure mode is very important
• A ductal failure yields a more controlled failure
that allows the car to still respond
Images from (IH8MUD 2013)
Control of the Failure
• The failure mode is very important
• Be careful of the failure type and consider the
yield characterises of the material that are
being considered for the design
Final Design
• The final design is in your groups hands
• Make sure to justify and evaluate all avenues
for the design
• Use any tool at your disposal to help with this
study
• Think about all the lectures and apply the
knowledge learnt to this design application

16. M39MAE ADAMS
We will continue to look at this in the
tutorials, these are just some guiding
note to help navigate around the model
Importing the Model
• The model required for the coursework along
with the loads that need to be applied can be
found on Moodle
• This file should be used for the simulations
• A further file which maps the displacement of
the tie rod can also be found
Running the Simulation
• To run the simulation you must put
the following simulation detailed in
• The solver needs to be changed from
“default” to “static”
• End Time = 1.0
• Steps = 200
• Once you are ready to run you need
to press the static equilibrium button
and then the play button
17. Changing the Wheel Loads
• To change the wheel loads for each
load case you need to go to the
menu and open the design variable
modify option
• This can be found in the menu
through
“Build/Design_Varaible_Modify
• You will then be presented with a
Database Navigation Window
• Only modify the variables that are
highlighted on the next page
Changing the Wheel Loads (continued)
• The following variable can be changed in
accordance with the wheel loads given:
f_lateral_force
f_longitudinal_force
f_vertical_force
m_lateral_moment
m_longitudinal_moment
18. m_vertical_moment
Changing the Wheel Loads (continued)
• Once one of the variables have
been selected press “OK”
• You will be present with
another dialog box
• Only change the “Standard
Value” to what is required for
the load case
• Then press “OK”
• You can then run the simulation
as described before to see the
effects of the loads on the tie
rod
Changing the Wheel Loads (continued)
• To change variable quickly you can right click in the
“Name” box and this will bring up browse which will then
bring up the database navigation page again
• Select the appropriate
force / moment you want
to modify and press OK
19. Reviewing the Results
• Once the simulation has
been run you should see
red lines or curves that
represent the force or
moment that you have
applied
• Check the right load has
been applied
Reviewing the Results
• To view the detailed results entre
the postprocessor
Reviewing the Results
• To view the displacements results use the
“Request” elements to see the x, y and z
displacements for each end of the tie rod
Reviewing the Results
• To view the forces in the joints change “Source”
to “Result Sets” and look at the joints called
20. j_toe_link_inner and j_toe_link_outer
Reviewing the Results
• Then the forces and moments can be selected to
see there response to the wheel loads

21. Assignment – Durability and Reliability of a car tie rod
The assignment involves evaluating a particular scenario (a car
tie rod) to design a component that can withstand particular
load conditions expected of the vehicle and to create a design
that will sustain the loads but also fail when intended to protect
other key parts. Overall, this coursework aims to assess a broad
spectrum of the subject as well as looking at a detailed study of
a particular scenario to evaluate the durability and reliability
theories.
For this assignment the students should work to evaluate a
particular scenario using the ideas and theories (and beyond
where appropriate). The aim of this study is to evaluate and
design a tie rod for a rally car steering mechanism. The tie rod
needs to be designed in such a way that it can sustain the
desired load case expected during “normal” operation of the
vehicle. Consideration then needs to be made such that if the
“normal” scenarios are exceeded, how the loads are managed
within the suspension system. This means looking to design the
tie rod to be a sacrificial element that will fail protecting the
more important / costly components of the suspension system.
Work details:
This coursework needs to be submitted in the form of a
technical report through plagiarism. The word limit for this
report is 5,500 words in the main body of the report.
-Some writing about What is a function, the purpose and
design of a car tie rod.
-What is reality force or loads and the problems come up in a
car tie rod part when the car working in different places and
different cases by technical analysis
-Coursework should contain case study, graphs, tables with
their references.
-All references must be a CU Harvard style with 15 references.
