The precision formation of the shaft cap is simulated by FEM. The divided flow method is available to reduce forming pressure and elastic deformation of die by analysing load stroke curve, stress ,mould deflection and so on.

• 采用有限元 (FEM)的方法对分流法精密成形端盖进行了计算机模拟 ,对坯料成形载荷 行程曲线、应力、模具的弹性变形等参量进行分析得出 :分流法是一个降低变形抗力和模具弹性变形 ,适于精密成形的有效的方法
