【Abstract】 By using the FEA and the orthogonal design to simulate the sheet stamping,we study the U-shape sheet metal.The orthogonal table firstly contains the material parameters,technology parameters and the die figure.We investigate the influence of parameters.Based on the results,we choose the significant parameters to array the springback experiments.By analyzing the data using regression analysis method,we can establish the mathematical model of the predicting of the springback of stamping.This method provides an effective way for the predicting of the springback in stamping.更多还原
