[Abstract]:Based on the variable density method, the interpolation model of multiphase materials is established, and the mathematical model of topological optimization of flexible mechanisms of multiphase materials is established, which aims at the maximum displacement of output points and restricts the volume of materials. The topology optimization of micro flexible clamp design is carried out by using moving asymptote method and the results are analyzed. The results show that the topology optimization method based on multiphase materials can greatly reduce the maximum stress level of the topological structure, but also reduce the displacement of the output point of the structure to a certain extent. On the whole, this method is feasible and can effectively solve the structural failure problem caused by excessive stress.
