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.

Innovative Design Analysis Solutions to Handle the Complexity of Modern Structures
This is a press article published by CAD User Magazine in June 2009.
"The signature buildings that architects love to put up these days might be designed to enhance the architect’s reputation along with the skyline of the client city, but their increasing complexities of shape pose significant challenges for the builders. In the first instance such large projects are never single sourced. They rely on close integration between a number of partners, each addressing significant issues. Secondly,
they come with demands for shorter development times with increased pressure to reduce engineering costs (engineering, because of the complexity of the projects, being a major cost element)."

The Application of Process Automation and Optimisation in the Rapid Development of New Passenger Vehicles at SAIC Motor
As a relatively young automotive company, SAIC Motor has drawn on the expertise of its UK Technical Centre to help in its objective to bring a new range of vehicles to market in an aggressive time frame. CAE has formed an integral part in doing this and the UK technical centre has worked closely with Altair Product Design amongst others to utilise its Engineers’ skills as well as the Hyperworks suite of software.
The paper aims to showcase what has been achieved to date, on the Roewe 550 medium car programme - currently on sale in China - and on another current vehicle programme, where processes have been developed further. Several interesting optimisation examples are highlighted in the development of the body structure as well as some key process improvement methodologies which have been jointly developed between SAIC and Altair to streamline the design process.

Evolutionary Design in Chassis Technology
This paper details the use of the Thyssenkrupp eDICT process for the design of sheet metal chassis components. eDICT (evolutionary design in chassis technology) is an innovative structured process flow for the design of optimal structures. eDICT uses the optimisation capability of Optistruct with a set of custom tools to guide and translate a design into a production feasible sheet metal solution. Fundamentally it reverses the usual design loop of CAD first then CAE assessment. The function is used to determine the design and the form follows. On recent projects eDICT has produced 25% mass reductions compared to the current series design. eDICT is also able to reduce development times and resource with an efficient solution production right from the outset.

FACTOR 001 is the result of a creative project by BERU f1systems to explore the transfer of design approaches, technology and materials from Formula One to a groundbreaking training bicycle. The design brief did not require the bicycle to comply with existing technical regulations, which resulted in great freedom during the design process. This paper details how OptiStruct Optimisation tools were used to help generate efficient lightweight solutions for the design of complex carbon fibre components. Free-size optimisation was used to generate laminate boundaries, ply thicknesses and fibre directions, which met stress and displacement requirements. Physical testing carried out on manufactured parts highlighted the accuracy of the FE models and demonstrated the advantages of incorporating OptiStruct Optimisation tools in the design process.

Biomedical Research at the Scripps Clinic: Modeling Orthopedic Implants with Altair HyperWorks
Every year, countless people — regardless of their age or level of physical activity — begin to experience the effects of osteoarthritis, a degenerative joint disease. As we age, the cartilage that cushions the joints begins to deteriorate. The head of the adjacent bones begin to break down from the friction, causing pain in the joint. When the condition worsens and non- surgical remedies are exhausted, surgeons may recommend joint replacement.
Typically, titanium alloy implants are lined with plastics that act as cartilage and are fixed in place with cement or screws by the surgeon. The implants can give patients a new lease on life, dramatically reducing pain and improving mobility. However, questions naturally arise in the patient’s mind: How much range of motion will I have in the new joint? How much strength will I recover? And how long will the new joint last?

CAE Process & Data Management Using Altair Hyperworks Solution
Computer-aided engineering plays a significant role in the product development process. However, with the growth in the number of simulations performed, and in the absence of
process and data management tools to track these simulations, inefficiencies start creeping into the CAE process. Altair Data Manager (ADM) is a pioneer tool in addressing this need. With this insight, the CAE group at Eicher Motors Ltd. decided to implement the ADM tool
before process management and data migration became a Herculean task. Eicher CAE users wanted the ADM system to help them manage the complete CAE process and improve CADCAE integration. That included automated assembly buildup of batch-meshed components; automated part library buildup; analysis iterations management; faster and consistent report extraction; centralized data storage without any data duplication; and efficient sharing of results and reports across the organization.

Optimization of the 787 Horizontal Stabilizer CFRP Composite Main Box
The -3 and -9 derivatives of Boeing's revolutionary 787 face a significant weight challenge due to very aggressive weight targets to achieve the desired efficiency. A major weight-trade study was launched to determine the optimal configuration and detail-sizing for the horizontal stabilizer CFRP co-cured main box. Using a genetic algorithm-based optimization solver (OptiStruct), various multi-spar configurations were optimized and evaluated. To determine the best path for further possible testing and allowable development, optimization was constrained to various buckling limits as well as to explore the addition of honeycomb core to both the skins and spars. The lowest additional development cost and risk, combined with a minimal weight, is chosen for each of the derivative models. Ultimately, the complete design of experiments highlights the development path toward the lightest possible composite main box structure.
