| 摘 要： | 工程结构的形状优化设计需要处理两类设计变量：尺寸和节点位置。由于两者量级不同，若同时考虑，计算量太大且收敛很慢。本文提出了分级耦合方法，将尺寸和节点位置分开处理，但在节点位置寻优过程中，必须考虑有利于下一轮的尺寸优化。

| Abstract: | In the process of shape optimization,both sectional areas and joint coordinates must be considered,but their order of magnitude is different.which makes computation huge and convergence slow. In this paper,a coupling multi-stage method is given,the solution process is di-vided into two stage,the sectional area variables are optimized at a fixed geometry,the joint coordinates are optimized at the fixed sectional areas. |
