Abstract
The ICM (Independent, Continuous and Mapping) method was applied to the frame structures. A topological optimization model for the frame structures under the multi-loading cases was established, which takes the weight as an objective function and subjects to the stress and displacement constraints. By using the smooth function and filter function, the discrete variables and continuous variables were transformed conveniently. Synthesized coordination between the topological solutions with the stress and displacement constraints under the multi-loading cases was considered. Numerical results show that the optimized frame structures are reasonable which are different from trusses.

将ICM(独立、连续、映射)优化方法应用于刚架结构,建立了以重量为目标函数、考虑多工况下应力和位移约束的刚架结构拓扑优化模型.借助于磨光函数和过滤函数,实现了离散变量和连续变量之间的相互转换.考虑多工况应力拓扑解之间、应力和位移约束下拓扑解之间的协调,得到了合理的结果.文中给出的刚架结构拓扑优化算例表明,刚架结构的拓扑结构不同于桁架或连续体.
