摘要
Abstract
To improve the crashworthiness and energy absorption performance,a novel crash box negative Poisson's ratio(NPR)structure is proposed according to the characteristics of low speed collision of bumper system. Taking the peak collision force and the average collision force as two subsystems,a multidisciplinary collaborative optimization design is carried out,and its optimization results are compared with the ones optimized by NSGA-II algorithm. Simulation results show that the crashworthiness and energy absorption performance of the novel crash box is improved effectively based on the multidisciplinary optimization method.关键词
