基于变复杂度近似模型的汽车安全性和轻量化优化
Study on Optimization for Automobile Safety and Lightweight Based on Variable Complexity Approximate Model
摘要
Abstract
Aiming at the complexity characteristics of automobile safety optimization considering the effects of stamping,a compensation response surface model was created by using optimal Latin square design through the small sample data spanning the traditional model and high accuracy model.And then a new Kriging response surface model was established on the basis of new test data which was created through the traditional model and compensation response surface model.A multi-objec tive particle swarm optimization algorithm was used to solve and optimize the response surface model.The method was applied to vehicle frontal impact and lightweight multi-objective optimization design.The results show that this method can ensure the response surface precision,rapid convergence to the optimal solution.关键词
