Structure Design of Stamping Die Based on Topology Optimization and Shape Optimization

Abstract

To quantitatively analyze the structural topology and control the elastic deformation of die structure in stamping, a new die structure design method was proposed. The forming analysis was conducted based on the die surface mesh generated in the third-party software. Structural analysis models were established according to the die surface mesh and deformation resistance obtained from forming analysis results. And then, the structure analysis and optimization were carried out. This new method for structure design of stamping die has two advantages. First one is the combination of forming analysis and structure analysis makes the structural optimization procedure more practical. Secondly, the coupling of topology optimization and shape optimization makes it possible to fundamentally change the structural topology and it is a new attempt to mold design.
