摘要
本文提出了一种杆系结构的拓扑优化设计方法。在本方法中,通过求解一个给出位移场的线性规划确定出结构的新的拓扑形式;将m个位移约束与n个应力约束等效为n个独立的应力约束;接着,利用专家系统技术对所得到的具有新拓扑的结构进行机动性分析並提供修改方案。几个数值实例说明了本方法的可行性。
In this paper, an algorithm for topology optimization design of trusses is presented. In the approach, the optimal topology structure is found by use of the simplex method. The m+n behaviour constraints are linked to n independent behaviour constraints. For the solution of Lp, displacement field must be given previously. In addition, the expert system is applied to the structural mobility analysis putting forward an improved scheme. Finally, several examples are given to demonstrate the algorithm.
