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.

A Comprehensive Process for Composite Design Optimisation
Composite structures offer unmatched design potential as laminate material properties can be tailored almost continuously throughout the structure. Moreover, composite laminate can be manufactured to fit the ideal shape of a structure for aerodynamic and other performances. However, this increased design freedom also brings new challenges for the design process and software. It is shown in this paper that optimization technology is well suited to exploit the potentials that composite materials offer.

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)."

Rapid Airbag Folding Technique for Side Curtain Airbag
TECOSIM has developed techniques which can shorten the folding & packaging process time to a few hours and still achieve the essential airbag deployment performance. We will present methods which rapidly fold a free mesh and allow for rapid shape changes for a detailed folded model. These methods can significantly reduce the turnaround time to incorporate design changes into the working CAE model for side impact and OOP [Out Of Position] studies. This technology can integrate airbag development further into the virtual world to allow ‘CAE led’ design of airbag profiles, chambers and seam lines to be established early in the design phase and establish a fully folded deployable airbag for all virtual phases.

Important tools associated with the scaling, and positioning of the model is also described. Secondly, an innovative model for scaling of human organs (individualization) is presented. The method which employs optimization techniques, identifies critical (optimal) anatomical control points which allow for a best scaled model of the HUMOS2 representing an individual. Finally, some remaining challenges for future human models are discussed and solution paths are described.

Automotive Modal Testing Support and CAE Correlation Using Altair HyperWorks
To derive the natural frequencies and mode shapes of a given structure, the test Engineer has to decide on excitation positions that will efficiently excite all the modes of the structure in the frequency range of interest. Excitation positions are usually decided upon from experience or trial and error methods which can be time consuming and still not capture all of the modes in the selected frequency range. Using Altair HyperStudy and Radioss (bulk), Pre-test CAE analysis has been carried out to identify effective excitation positions before the commencement of modal testing, thereby significantly reducing pre-test lab time.

Keeping ahead of the competition by bringing new and exciting products to market faster whilst maintaining quality, presents a major engineering challenge. A new packaging development process is described, which introduces advanced automated simulation and optimization technology right from the concept development phase. Detailed predictions of primary, secondary and tertiary packaging performance are made possible through use of advanced simulation technology. Design optimization is then employed using the modelling as a virtual testing ground for design variants. The approach provides clear design direction, an opportunity for wider experimentation, helps to improve performance and reduces uncertainty in the development 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.

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?
