多相材料的柔性机构拓扑优化设计
Topology Optimization Design of Compliant Mechanisms for Multiphase Materials
摘要
Abstract
Based on the variable density method,the interpolation model for multiphase materials is established,and the topology optimization model for the compliant mechanisms with the maximum displacement of the structure and the material volume as the constraint is established.The miniature flexible clamp for example,with the Method of moving asymptotes(MMA) to complete the calculation,and the topology results are analyzed.The results show that the topology optimization method of compliant mechanisms for multiphase materials is feasible,which can significantly reduce the maximum stress level of the topology structure,but also to a certain extent,the displacement of the output point of the structure is reduced.As a whole,the method is feasible,and can effectively solve the problem of structural failure caused by excessive stress in the project.关键词
