The application of response surface method and orthogonal experiment design in the optimum design for drawbead geometry parameters

Abstract

Drawbead geometry parameters have a significant effect to the quality of sheet metal forming. The application of response surface method (RSM), orthogonal experiment design method (OEDM) and dynamic explicit finite element method (FEM) in the optimum design (OD) for drawbead geometry paroameters used in drawing procedure of cross member panel, a benchmark of Numisheet'2005, was discussed. The comparison between the OD results and the drawbead geometry parameters offered by the benchmark was carried. The effectiveness of this method was verified. © 2010 IEEE.
