摘要
悬架系统是电动汽车的重要组成部分,而下控制臂是汽车悬架系统传递运动的关键构件,它可以将车轮的力传递给车架,同时控制车轮的运动.随着电动汽车轻量化逐渐成为企业的研究热点,研究人员对电动汽车零部件的优化设计做了大量的研究工作.该文基于SIMP方法对某电动车下控制臂进行了拓扑优化设计,优化后的下控制臂重量减轻了 33%,通过有限元分析方法对优化后的下控制臂进行了力学分析,验证了优化后的下控制臂的强度和刚度均满足要求.
Abstract
The suspension system is an important component of electric vehicles,and the lower control arm is a key component for transmitting motion in the suspension system.The lower control arm transfers the force of the wheels to the frame and con-trols the movement of the wheels.With the increasing trend of lightweight electric vehicles becoming a hot research topic for enterprises,researchers have conducted extensive research on the optimization design of electric vehicle components.In this article,the topology optimization design based on SIMP method was carried out on the lower control arm of an electric vehicle.The weight of the optimized lower control arm was reduced by 35%.Then the mechanical analysis was conducted on the opti-mized lower control arm through finite element analysis,and it was verified that the strength and stiffness of the optimized low-er control arm meet the requirements.
