| 摘 要： | 根据离散变量结构优化设计的特点，提出了离散变量结构优化设计的单向搜索算法。算例结果表明，该方法能直接计算具有应力约束和截面尺寸约束的离散变量结构优化问题，也能处理同时具有稳定约束和位移约束的多工况、多约束、多变量的离散变量结构优化设计问题。设计的结构强度和刚度等都有了保证，重量轻，成本低。

| Abstract: | According to the characteristics of structural optimum design with discrete variables, one-way design method is presented for structural optimum design with discrete variables. The results of examples expatiate that this method can be used directly to work out the structural optimum design with discrete variables, which involve the stress constraints and cross-section size constraints. The method can also deal with the structural discrete optimization with multi-variables, multi-loading and multi-constraints.The designed structure features high strength rigidness, light in weight and low in cost. |
