考虑位移约束的功能梯度结构ICM拓扑优化方法
ICM Topology Optimization Method of Functionally Graded Structures Considering Displacement Constraint
摘要
Abstract
Topology optimization of functionally graded material structure was presented based on independent continuous and mapping method.By introducing the filter function,the FGM-ICM model was constructed.Combined with the gradient displacement function,the approximate explicit model for ICM structural topologyoptimization of FGM was established.The filter method of linear attenuation was adopted to avoid the checkerboards and mesh dependency problem.Meanwhile,in order to obtain the clear topological configuration,the dynamic adjustment strategy for the topological variable threshold was proposed.The results of numerical examples demonstrate that the proposed analysis method can effectively realize the structural topological optimization of FGM.关键词
