Discovering Optimal Material Parameters and Design Alternatives

摘要

To develop passive vehicle safety systems, leading automotive manufacturers employ physical crash dummies as well as their virtual counterparts. Using accurate digital dummy models provides time and cost savings by reducing reliance on physical testing. The Abaqus WorldSID 50th per-centile (WorldSID50) virtual crash-test dummy model comprises approximately 260,000 elements and more than 20 different materials. Developing this model required evaluations of hundreds of model parameters to achieve good correlation with test data under different loading conditions and rates.
