基于全局敏感性分析和 Kriging 代理模型的汽车乘员约束系统多参数优化研究
Study on Multi-parameter Optimization of Occupant Restraint SystemBased on Global Sensitivity Analysis and Kriging Model
摘要
Abstract
Aiming at the problems of multi-parameter and high nonlinearity in the optimal design of occupant restraint system,a method of parameters global sensitivity analysis based on Kriging mod-el was raised.This method evaluated the sensitivity of each parameter through calculating the contri-bution of design parameters to the variance of response.On the basis of these data,the design parame-ters which were more important to response were chosen as optimization variables,additionally.Multi-island genetic algorithm was used to realize optimal design.The results of optimal design indicate that in contradistinction to initial design values,the value of human injury WIC(weighted injury criterion) is reduced by 1 1.9%,it provides a good reference for actual engineering design.关键词
