Abstract
This paper built the 100% frontal crash model of the minibus, 8 thickness of the components which have obvious effect on vehicle crash performance were selected as design variables, and choose the appropriate evaluation index as the responses. Use DOE experimental design method to get 70 set training data and built Kriging approximate model based on the training data. The approximate model is optimized by PSO algorithm, in the optimized scheme, the a
max and m has decreased by 7.6% and 0.87%, D1, D2 and D3 has decreased by 7.7%, 3.1% and 5.3%.
