Development of a topological optimised Hinge Arm through combination of ALM- ...Altair
Since 1974 TITAL GmbH manufactures high quality castings from aluminium and titanium alloys solely according to the lost wax process, mainly for the aerospace industry. The advantage of this process, besides its high dimensional accuracy and excellent material consistency, is the optimised use of material as this process enables the implementation of complex geometries such as undercuts etc. Because of this, topological optimised designs can be realised with nearly no limitations. This is possible because of the use of lost patterns and lost molds. For prototypes and small production batches such patterns are built using ALM-processes as SLS- or SLA-parts. The combination of topology optimisation, generative manufactured RP-models and the investment casting process enables the designer to realise operational prototypes at maximum flexibility without loss of quality. Further advantages of this combination are the feasible part sizes, as well as the unrestricted usability of such parts because of the well-established and approved processes. As a case study the development of the Hinge Arm for the Chinese passenger aircraft COMAC C919 will be presented, which has been topological optimised with the support of Altair Engineering GmbH in Munich (Unterschleißheim).

Advantage of LED Street light with ‘ALG Engine’
Lowest Power consumption compared to other products (nearly half of other LED lights)
Our patented ‘Cooling Fin system’ guarantees the LED lights quality over the life span of 50,000 hours as the patented technology keeps cooling the LED lights system most efficiently no matter how the surrounding temperature soars up.
It retains almost same luminosity even when it lights the ground of up to ,say, 12m apart from the light source while the luminosity of most of other makers tend to decrease drastically when the LED street lights illuminates the ground of such a distance.
The life span is approx. 50,000 hours, which is monumentally big difference from others on the markets.
Its weight is very light, almost one-third less than the others, as the casing is made of polycarbonate material instead of die-casting that most of other makers are using. Thus it makes the installation work easy and so much, the installation cost could be lowered.
It is designed to be very rugged and strong to any external impacts
It is designed to secure perfect water-proof.
With such technical superiority and advantages, it does have unrivaled price competitiveness.

Enterprise Excellence is Inclusive Excellence.pdfKaiNexus
Enterprise excellence and inclusive excellence are closely linked, and real-world challenges have shown that both are essential to the success of any organization. To achieve enterprise excellence, organizations must focus on improving their operations and processes while creating an inclusive environment that engages everyone. In this interactive session, the facilitator will highlight commonly established business practices and how they limit our ability to engage everyone every day. More importantly, though, participants will likely gain increased awareness of what we can do differently to maximize enterprise excellence through deliberate inclusion.
What is Enterprise Excellence?
Enterprise Excellence is a holistic approach that's aimed at achieving world-class performance across all aspects of the organization.
What might I learn?
A way to engage all in creating Inclusive Excellence. Lessons from the US military and their parallels to the story of Harry Potter. How belt systems and CI teams can destroy inclusive practices. How leadership language invites people to the party. There are three things leaders can do to engage everyone every day: maximizing psychological safety to create environments where folks learn, contribute, and challenge the status quo.
Who might benefit? Anyone and everyone leading folks from the shop floor to top floor.

In this deck, you will learn the significance of workplace discipline for organisational success. You’ll also learn
• Four (4) workplace discipline methods you should consider
• The best and most practical approach to implementing workplace discipline.
• Three (3) key tips to maintain a disciplined workplace.

8. Hall Herault Process (cell stability)
CE Maintaining cell stability
'Smelters need to maintain stable operating conditions so that energy and
carbon are consumed in such a way that aluminium production is optimized
and greenhouse gas emissions are minimized,' says Dr Lwin, from CSIRO's
Mathematical and Information Sciences division.
Cell operation is controlled by three variables:
– anode-cathode distance (ACD)
– alumina concentration in the cell bath
– and heat-balance in the cell.
The control of these variables depends on
monitoring and assessment of measurable
signals:
– Cell resistance and/or voltage, meausred during the
electrolysis from the cell
'Abnormal patterns in the voltage signal, for example, trigger actions such as
varying the ACD, or breaking the crust of the cell and feeding it with
alumina.‘
kWh/T Preliminary results indicate that early warning alert systems for detecting
certain abnormal patterns are achievable
.
Dr Lwin says the signal analysis project team is collaborating with three major
aluminium companies.

9. Typical KPI’s In Al Industry
• Current efficiencies : >95%
– Actual production per cell = Theoretical Production x CE/100
– Where Theoretical Production = Current x 0,08056 (Ton/Day)
• DC power consumption: <14 kwH/T
– kWH/kg = Volts/CE x 298
• Output Smelter:
– Output = Actual per cell x number of cells x 365
• Capital Charge: <$700/YT production
