对离散变量结构拓扑优化设计几个问题的探讨

Study of some problems of structural optimization with discrete variables

探讨了离散变量结构拓扑优化的三个问题．指出离散变量拓扑优化也存在所谓奇异拓扑的现象；指出设计变量的离散程度和位移约束影响最优拓扑，优化设计时不可忽视．

Three problems of structural optimization with discrete variables are studied. The facts are pointed out that the so called singular topology exists in discrete topology design and the optimum topology may be controlled by discreteness of design variables and displacement constraints, thus can not be neglected.
