Research on Topology Optimization Method of Large Structure Using Diffusion Mapping of Local Structure Characteristics
A new topology optimization method is proposed to solve the problem that existing topology optimization methods perform global topology optimization on the variables in the designated design domain,which leads to the loss of the optimal topology distribution information in the local area during topology optimization of large components.This method firstly optimizes the topology of the local area in the design domain to obtain the local optimization information in the design domain,and then integrates the local area optimization information to obtain the global topology.Compared with the existing commercial software ANSYS Workbench and global optimization methods,the results show that the proposed optimization method can better retain the local topology structure information in the design domain and can control the size of the optimized structure.
