具有多种约束的连续体结构拓扑优化

Topological Optimization of Continuum Structureswith Various Constraints

对于具有多种约束条件的连续体结构的拓扑优化设计,本文提出一种通用优化方法:首先用优化方法确定微孔或称为基点的位置,然后再扩大微孔并确定其边界.文中对于具有应力和位移约束的几个平面问题进行拓扑优化,计算结果十分令人满意.

A optimization method described in this paper can be applied to the topological optimization of continuum structures with various constraints perfectly. It performs the optimization in two steps.First, resolves the problem of which region in the elastic continuum should be deleted. Second, locates the boundary of these regions. This method can be used to resolve the optimization problem of any kind of constraints. The final result of the topological optimization of continuum structures with various constraints of stress and displacement by using the method described in this paper is perfect.
