| Abstract: | Topological optimization theory was enunciated in this paper, and variable density topological optimization method was used to analyze the rear platen's structure of injection molding machine by ANSYS software. The optimal structure was found out and it had lower stress and strain than original. Topological optimization method gave the theory base to improve the platen's structure, and it was useful for solving practical problems. |
