摘　　要：分析了传统钣金结构车身的静态刚度和动态特性,基于该钣金结构车身,采用结构优化工具,根据电动车的性能要求设计出了骨架式电动车车身,经过对比分析,验证了骨架式结构车身在实现轻量化设计的前提下,性能还有所提升。为电动车车身的结构设计提供了一条新的设计思路。First, the static stiffness and modal performances of traditional sheet metal structure bodies was analyzed. Then based on the sheet metal structure body, using structural optimization tools, the skeleton electric vehicle body was designed according to the performance requirements of electric vehicles. After comparative analysis, it was verified that the frame-type structure body has certain advantages of lightweight as well as performances. This paper provides a new design idea of electric vehicles structure designs.
