MAHLE's Switch to HyperWorks
This was a 2010 Americas HTC Presentation given by Scott Janowiak from Mahle. Recently in the auto industry, there has been a high demand for smaller, lighter, and more efficient engines. The piston and connecting rod have a major impact on the performance of an engine; therefore optimizing these parts is essential. With the help of HyperMesh, advantages for meshing were noticed immediately. HyperMesh allowed Mahle to increase the mesh quality by using tools which helped increase mesh speed and efficiency.

HyperWorks Improves Development Processes in Automotive Industry
In 2008 PWO Germany (Progress-Werk Oberkirch AG) had to develop and produce a new steel made automotive cross car beam (CCB) for the dash board of a new car. PWO received the CAD model, the design space definition and other pre-defined standards of the component from the customer and developed and produced the fitting cross beam based on this information. PWO used the HyperWorks Suite to develop the component. HyperMesh was used to transfer the CAD model into a FEA model, which was then used to run dedicated analysis and simulation tasks. To fulfill the requirements for crash and modal analysis, the company used OptiStruct to optimize the component, RADIOSS and other external solver to run the calculations and HyperView for the post processing. HyperForm was used to check the production feasibility of the individual components and for metal forming simulation tasks. It was important for PWO to have a software suite available that could cover all simulation tasks within one graphical user interface and licensing system.

HyperMesh and HyperView customization for thermal analysis of engine systems
This was a 2010 Americas HTC Presentation given by Emil Chouinard from GE Aviation. GE Aircraft Engines has many NPI (new product initiative) programs that rely on accurate and timely thermal analysis, as temperatures are critical to accurate estimates of hardware life. HyperMesh and HyperView have been customized as the pre and post processing tools, respectively, for thermal analysis of engine systems. The single database with relational data management greatly reduces modeling errors and results in Engineers being able to focus on the physics of the problem instead of data management.

Hawk T Mk2 - Arrestor Barrier (BAN MK2) Engagement Analysis
As the UK Ministry of Defence (MoD) Design Authority for Aircraft Arrestor Barrier Nets, AmSafe products are used to stop aircraft from over-running the end of the runway. The British Arrestor Net (BAN) Mk2 is suspended across the runway over-run area by two electrically driven stanchions and raised or lowered by remote control from the Air Traffic Control tower. This paper describes the process and results of a FE analysis of the engagement of the Hawk T Mk2 aircraft into a Type A Barrier (BAN Mk2). The analysis was performed using RADIOSS, an advanced non-linear explicit Finite Element solver.

Fast Tracking Rail Vehicle Design
Bombardier Transportation UK offers one of the most comprehensive and diverse rail vehicle portfolios in the world. The strategy is one of continuous development that provides the most effective and cost-efficient rail solutions for today and the future. A key ingredient is the use of Altair HyperWorks enterprise computer aided engineering (CAE) solution. Altair's technology is now present at every stage of the design process and has increased the efficiency of the product development process. The paper details how Altair tools have been used to generate Finite Element (FE) models of carbodies, bogies and secondary structures in reduced time scales. Significant weight and cost savings are achieved through structural optimisation of components such as large steel castings, aluminium extrusions and steel fabricated structures which are subjected to linear static, fatigue and abuse loading. Automated post processing facilitates the interpretation of results and the writing of detailed official reports.
