The friction among the die,punch and clamp in deep drawing has been studied by using the finite element model and ANSYS/LS-DYNA software. The effect of friction factors on metal blank deep drawing process has been investigated.

• 基于该有限元模型和ANSYS/LS-DYNA软件平台，分别针对板料与凹模、凸模、压边圈间摩擦进行了三维有限元分析，探讨了板料拉深成形过程中摩擦因素对板料应力应变分布规律的影响。
