MSC.Software: User Case Study - Proton USER CASE STUDY PROTON Customer Profile: Noor Hisham Bin Ismail Mr Noor Hisham Bin Ismail is head of CAE at PROTON based in Kuala Lumpur, Malaysia. Mr Ismail and other members of the computer-aided engineering team are responsible for improving the virtual development of mechanical and structural components, sub systems and complete vehicle system at PROTON. Through Mr Ismail’s innovative process of probabilistic analysis, PROTON has been able to effectively identify areas of high-risk failure and fine-tuning engineering design alternatives. Challenge Mr Ismail’s foundation of probabilistic design methodology uses design In developing complex mechanical and structural automotive criteria based on reliability targets instead of deterministic criteria. components, going through multiple build-and-test hardware prototype First, design parameters such as applied loads, material strength, and cycles to verify performance, stress and fatigue life is just too time- operational parameters are researched and/or measured and then consuming and expensive. This issue can be addressed by evaluating statistically defined. A probabilistic analysis model is then developed for and refining designs with analysis tools up front in development, reducing the entire system and solutions performed to yield failure probabilities. test cycles later in the development process. PROTON’s pioneering spirit With MSC’s FEA, applied stress is obtained from finite element models. naturally has led Mr ismail to not just stop at traditional methodologies in The general concept is to integrate the joint probability of applied stress computer-aided engineering for design analysis. As the risk of failure in and material strength over the region where stress exceeds strength. The any design was becoming result of the integration is the probability of structural failure and this helps more and more significant to provide the necessary information for sensitivity analysis and design and he was constantly optimization. looking at areas to assess Relying on industry- risk parameters and minimize leading solutions such any risk factors, he needed as MSC’s FEA and to turn to industry-leading Adams, Mr Ismail is able simulation analysis tools that to build a “Reliability would be able to provide him Engineering” framework with the necessary accurate that provided the foundation to progress his foundation for accurate methodology. Mr Ismail Basic Stress and Material Cyclic Strength analysis. realized that conventional With MSC, Mr Ismail is virtual development approaches are no longer sufficient to meet the able to conduct multi- increasing standards of accuracy required at PROTON. Conventional Yield Stress and Operating Stress Performance run design improvement approaches do not take into consideration the variations that affect finite studies which can be used to assess design sensitivity to product and element analyses. Mr Ismail needed proven tools that produced the most environment variability, discover unknown design variable interactions, accurate results, allowing him to capture the potential failures and provide and provide a global view of the overall design space. the nature of failures so that these can be mitigated in the process. With resource efficiency on his mind, Ms Ismail also needed to manage test But the analysis does not stop here; as Mr Ismail has further incorporate accuracy while reducing the dependency on running too many variations. his finite analysis results in a stochastic simulation via the Monte Carlo technique that provides the statistical results of the variation distribution. Solution Mr Ismail then further combines the results with critical parameters MSC FEA (MSC Nastran and Patran),MSC Adams. yielding an even stronger and more robust solution. Benefits “All critical elements derived from simulation results are subjected to • Visible quantification of design risk or reliability additional quantifiable risk analysis, this helps to mitigate probability • Identifies areas of high risk in a design of failures later during the development stage,” said Mr Noor Hisham • Provides the ability to modify design variables relative to reliability bin Ismail, PROTON Holdings Berhad. “Computer-aided engineering technology has provided the foundation for PROTON’s success in a highly • Provides a means to compare differing designs competitive automotive industry. With MSC.Software, we have been able Case Study to cut costs while improving quality and reducing time-to-market. Our PROTON can shorten the time-to-market by getting designs right the first drive for engineering innovation will enable us to continue enhancing our time. Many of PROTON’s automotive components need extensive lead competitiveness by improving our engineering development process and times because of its strict adherence to safety and quality standards. driving production efficiency.” Besides, traditional physical testing can take weeks or even months to validate a design. Leveraging analysis early in the process can eliminate unforeseen changes and repetition of lengthy test cycles, providing significant reductions in overall development time.
