J0201-1-4 Mechanism Analysis using CAP for Occupant Protection Performance in Side Impact

Abstract

The progress of CAE technology and the improvement of computer performance enabled dummy readings prediction with high accuracy by full virtual analysis. Meanwhile, increasing number of test configurations in US regulation and NCAPs of side impact makes it difficult to design both BIW and restraint system. To solve this issue, it is important to understand the law of causality regarding dummy readings. Therefore, we applied CAP, Computer Aided Principal, which is a method for finding the indications of how the phenomenon occurs, to the full virtual analysis. The results showed that some interaction exists in the relationship between IIHS and SINCAP regarding dummy readings.
