摘　　要：根据某无人车外定子轮毂电机和双横臂独立悬架的外形尺寸,设计了不同于传统结构的转向节,并采用Adams软件和Hyper Works软件分别进行了动力学计算、刚强度分析和结构的拓扑优化研究,结果表明转向节刚强度小于材料的许用应力,重量轻巧,符合设计要求。According to the overall dimension of the outside stator hub motor and the double wishbone independent suspension, knuckle is designed differently from the traditional structure. Adams software and HyperWorks software are used for the dynamic calculation, the stiffness analysis and topology optimization. The resuhs show that the stiffness of knuckle is less than the allowable stress of the material and light weight, which meet the design requirements.
