Robustness Optimization Design of Bumper Structure Based on Protection of Pedestrian Lower Leg
摘要
Abstract
In order to improve lower leg protection of bumper structure,this paper presented a systematic method combining experimental design,radial basis function approximation modeling tech-nology,the global optimization algorithm and 6-Sigma quality design based on Monte Carlo simula-tion,which was applied to optimize the bumper structure.Due to taking the uncertainty of design variables into consideration,the optimization results are more reliable and robust than that of the de-terministic optimization method.Therefore,to some extent,this paper proposed a robustness optimi-zation design method for solving complex engineering problems,and further application of this meth-od can improve the design quality of products greatly.关键词
