Key technology of mixed response method for absorbing member of auto
混合响应面法对汽车吸能部件优化关键技术

A new mixed response surface method combined with sequential response surface method, successful response method and Kriging interpolation method was proposed for high dimensional problems. The sequential response surface was employed for producing coarsen response surface. And then, the Kriging interpolation method was used for constructing the better robust surface to decide the better initial values of design variable and reduce constraints to in considerable range. Finally, the successful response surface was applied for finding the best optimization result, The shell thickness of front side member of auto was optimized by suggested method and got better result.
