摘　　要：敞篷车顶盖总成和部分侧围关键接头缺失导致扭转刚度较低的问题,论文以提升敞篷车扭转刚度为目的,通过有限元软件OptiStruct模块对敞篷车下车体空间进行拓扑分析,解析扭转工况车身拓扑传力路径,结合工程实际情况,提出在电池包底部增加抗扭管梁方案,且抗扭管梁与电池包螺栓连接,使得敞篷车身扭转刚度提升51.2%,效果显著。In order to improve the torsional stiffness of the convertible,the topological analysis of the body space under the convertible is analyzed by the Finite Element Software OptiStruct module,the topological transmission path of the torsional working body is analyzed,and the scheme of adding the torsional pipe beam at the bottom of the battery pack is proposed in combination with the actual situation of the project,and the torsional pipe beam is bolted with the battery pack,which increases the torsional stiffness of the convertible body by 51.2%,which has a significant effect.
