| 摘 要： | 对桁架结构的布局优化方法进行了初步的探讨，首先仅考虑平衡方程和应力约束，形成线性规划模型，以此确定最优拓扑结构；然后在此拓扑结构下，考虑平衡方程、变形直辖市条件和各种性态约束，形成非线性规划模型，以此确定形状和尺寸。

| Abstract: | In this paper.preliminary study on method of optimal layout design was made.In the first place,consider-ing equilibrium equations and stress constraints,the linear programming model was formed and the optimaltopology was established.Then the nonlinear programming model was formed considering equilibrium equa-tions,cormpatibility conditions and various performance constraints. Based on the obtained topological structure,the shape and sizes were established. |
