摘　　要：对一种对多功能结构设计封装提出了拓扑优化设计方案,利用渐进结构优化的方法,在Pro/E中建立简化的模型,再导入到Hyper Mesh中指定需要优化的区域,设定为目标函数,进行模态分析。我们的要求是让材料利用率最大化,也就是使结构的材料分布最优化。通过模态的对比看出达到了设计要求。This paper shows a multi-functional structure, which is used for a spacecraft. Its designs based on an existing circuit diagram. In order to improve its mode, topology optimization is done by the following three steps, first, building the model in pro/e and leading into the hyper mesh. second, meshing the model with the reasonable size; third, assigning the region, which needs to be optimized and established for the objective function. It concludes that the mode is improved by the comparison.
