摘 要：The performance of the aluminum alloy makes it the most popular lightweight materials for the automobile manufacturers.However,due to the disparity on the crystal structure,it has the higher springback values compared with steel.In order to solve the problem,we put forward a new springback compensation method based on displacement compensation principle and the principle of curved surface fairing design methods.Though full cycle simulation and calculate springback value for each working procedure,then generate the springback compensation surface.The method's practical application effect is good.
