| 摘 要： | 通常的结构拓扑优化是在给定外部作用下的构型设计. 然而对于复杂结构，
各部件由连接构件相连并通过它传递外部作用，所以连接方式影响部件承受载荷的分布，即
连接构件的布局对部件的最优构型有重要影响. 研究结构部件构型与部件之间连接方式
的协同优化问题，在连接区域引入一种特殊的材料模型，以材料的分布描述连接方式. 将承
力结构与连接构件域的材料密度同时作为设计变量，提出了一种基于拓扑优化思想的连接方
式与结构拓扑优化协同设计的优化模型和相应的求解方法. 给出的算例证明了这种设计方法
与优化策略的有效性.

| Abstract: | The conventional structural topology optimization is to design the structure layout with fixed external loads.In addition,the linkage model of components in a structure has a great influence on the optimal topology design of structure layout due to the load transfer function of components connection.This paper was focused on concurrent optimum design of components layout and connection in a complex structure. First,a new type of material model was introduced in the connective domain and different material d... |
