Multidisciplinary Simulations Provide a Pathway to Lightweight Automotive Systems

This presentation was made at NAFEMS Americas Seminar "Engineering Analysis & Simulation in the Automotive Industry: Creating the Next Generation Vehicle Accurate Modelling for Tomorrow's Technologies".

The automotive engineering community is now confronting the largest technology transformation since its inception. This includes the electrification of powertrains for more efficient consumption and cleaner emissions, the reinvention of the battery with fast wireless charging capabilities and finally the advent of a fully autonomous vehicle. Compounding to these technology changes, the automotive companies design verification process is moving away from a major reliance on physical testing to almost a full virtual simulation product verification process. The challenges to the automotive engineers are enormous and require a significant increase in the upfront use of numerical simulation capabilities, methods and processes such they’re able to efficiently design, manufacture and deliver these very innovative technologies to the market in greater speeds than ever before.

Resource Abstract

As propulsion systems move more aggressively to battery electric architectures, the motivation and urgency to reduce automotive structural weight is even more important. This emphasis on lightweight systems presents new challenges for NVH, durability and Crashworthiness development, and the interaction between these once-siloled domains. Simulations are also being challenged to be more accurate as reliance on testing is reduced and the development risks have increased. MSC is providing enhanced simulation solutions that address these challenges

Challenges also exist for the developers of software tools used to simulate complex interactions between the various attributes, such as durability and NVH, or aerodynamics/flow and acoustics. The need for multi-physics (multi-discipline) simulations has encouraged the development of co-simulation strategies and dedicated user interfaces that enable use of multiple software to solve multi-physics problems.

Case studies will be presented that highlight the use of multi-physics simulations and not only the successes, but also the challenges that face engineers developing the next generation of vehicles and innovative solutions that are being provided by the CAE software industry.
