An Approach on Robust Design Optimization of Side Impact Crash Analysis Using FEM and DFSS 2008-01-0359

It is well known that the variation of analysis parameters is a significant concern for the crash simulation of safety performance on occupant protection using FEM. In this work, an approach of DFSS (Design For Six Sigma) using approximation model is proposed to take account the variation on material and dummy position into the robust design optimization in the detail design stage of crash performance. As a result of this work, the mean value and deviation of the injury indices such as chest deflection and pelvis force are reduced and the sigma level of objective index is increased.
