摘要：

This paper deals with the optimization of process parameters in high strength sheet metal forming in order to reduce the springback effects after forming. The optimum parameters including holder force, friction coefficient and die radius which influence springback are studied through numerical simulation and orthogonal experiment. For predicting the springback accurately, the uniform experiment was used and BP neural network model was built up. The results show that springback of the front side rail is seriously influenced by these parameters, and the springback under the case of giving a group of process parameters can be predicted by the BP neural network model.
