摘　　要：高强钢和铝板的回弹明显大于普通钢板,有必要进行理论分析。计算回弹时,模拟条件尽可能和现场条件一致,需注意摩擦系数、压边力和修边工序具体设置。针对现行做符型的方法(CAD法和夹持法)的不足,提出了一种新方法——压型法。The springback of high-yield steel and aluminum is higher than low-yield steel.It is necessary to analyze the reasons theoretically.In springback simulation,the parameters,such as friction coefficient,blankholder force,tools in trim operations should be set according to the conditions in workshop.In order to solve the deficiencies of two methods(CAD and clamping)that prevail at current time,a new method(crashform)is introduced.
