均匀设计是试验设计方法的一种。采用有限元技术和均匀设计方法对筒形件在拉深成形过程中的摩擦系数、压边力、凹模口圆角半径等工艺参数进行优化设计。优化后的仿真结果在提高成形裕度和抑制厚度的变化方面取得很好的效果。该方法还可以明显减少模拟计算次数,提高优化效率,改善板料冲压成形的仿真计算精度。

Uniform design is a type of experimental design methods.This paper uses the finite-element technology and uniform design method to optimize processing parameter of cylindrical cup, such as friction coefficient, blank-holder force and top radius of die during the course of deep drawing.Simulation results show that there is a good effect no improving forming tolerance and restricting variable thickness .The method can reduce simulation frequency, increase optimization efficiency and improve simulation calculating accuracy of sheet stamping
