The Robustness Simulation Parameter Design of V-shape Stamping Process Based on FEM and Taguchi Method

An effective method based on finite element method and Taguchi method to solve the problem of the robustness parameter simulation design for stamping process was given. The key parameters which affect the modeling and simulation of V-shape stamping process were analyzed, The factors and their levels were studied and confirmed. Whereafter the finite element software ABAQUS was used to build the simulation model for V-shape stamping process. The Taguchi method was used to make out the robustness design. By comparison between the practical and simulation experiments, it can be concluded that the simulation design is reasonable. The proposed method extends the Taguchi method and provides a simple and effective solution for parameter robustness design.
