双向插值模式算法在拓扑优化中的应用

摘要

提出双向插值模式的插值处理算法，详细介绍该种优化算法的流程，对其进行验证。分别用只对敏度进行双向插值、同时对刚度和敏度进行双向插值、各向材料惩罚密度法模式算法对基本结构进行拓扑优化分析。结果表明第一种模式算法拓扑结构简单，更具全局收敛性。%In this paper we present an interpolation processing algorithm with bidirectional interpolation pattern,and introduce in detail the process of this optimisation algorithm,as well as carry out the verification on it.Moreover,we conduct the topological optimisation analysis on the basic structure using the pattern algorithms of bidirectionally interpolating the sensitivity only,bidirectionally interpolating the rigidity and sensitivity both simultaneously,and anisotropic material punishment density method respectively.Results show that the topology structure of the first pattern algorithm is simple,and has the global convergence more.
