ULSAB-Advanced Vehicle Concepts: Safety/Crash Management

The goal of ULSAB-Advanced Vehicle Concepts (AVC) is to develop a platform with the highest number of shared parts possible between two vehicle classes -European C-Class and the North American PNGV-Class concepts. Aggressive targets for mass and safety are considered --all the while maintaining affordable cost and achieving safety goals anticipated for 2004 and beyond. The objective of the CAE analysis of crashworthiness for ULSAB-AVC is to analyze and optimize the vehicle structure to provide the opportunity for development of complete vehicles that will obtain excellent star ratings. This paper will discuss crash safety and crash energy management aspects of the ULSAB-AVC, including important considerations for selecting advanced high-strength steels for crashworthiness applications, body-in-white design and materials selection procedures, BIW concept design and major load paths, and performance against crashworthiness targets.
