| 摘 要： | 针对车身结构在概念设计阶段出现的拓扑优化结果不连续,结构优化设计周期时间长等问题,基于optistruct优化软件,提出一种拓扑和尺寸组合优化模型.该模型可以同时进行尺寸优化和拓扑优化设计,得到车身蒙皮优化尺寸和最优的车身骨架加载路径,同时缩短了结构的概念设计阶段的设计周期.以ATV车身的结构优化设计为研究对象,对比优化前后的分析结果,在不降低结构性能的前提下优化后的结构减重105.5kg,验证了该方法的可行性.

| Abstract: | In order to overcome the problems of discontinuous topological optimization results and the long cycle time of carbody structure optimization in the conceptual design stage,an optimization model that combines topology and size optimization was proposed.The method can not only obtain the best size and loading paths of body frame,but also shorten the cycle time.As an example,a body structure of ATV was optimized with 105.5 kg being reduced of the structure. |
