摘要

针对纯电动汽车尾部耐撞性要求,采用结构拓扑优化和正交试验设计相结合的方法,以国内某款纯电动汽车为实例,通过建立车尾拓扑优化模型,有限元模型,尺寸优化模型,在满足碰撞安全性法规前提下,以实现最优整车加速度和汽车尾部吸能区吸能量为两个优化目标,对纯电动汽车尾部进行优化设计,最终得出合理的优化构型,实现对电动汽车尾部耐撞性的优化设计。

Abstract

For the pure electric vehicle rear crashworthiness requirements,this paper combined structural topology optimization with orthogonal design. Referenced a domestic pure electric car,by establishing vehicle tail’s topology optimization model,finite element model,size optimization model and for achieving optimal vehicle acceleration and energy absorption of car rear crumple zones under crash safety regulations,optimized the design of pure electric car tail. Eventually get a reasonable optimized configuration and realize the pure electric vehicle tail optimization of the crashworthiness design.
