摘　　要：锻造生产条件复杂,操作机夹持界面的接触状态容易发生改变,继而影响到钳口夹持稳定性。本文通过有限元数值模拟方法,对锻造操作机夹持界面的静态力学特性进行了研究。重点讨论了锻件不圆度、夹持界面摩擦系数、钳口角度、锻件大小等系列参数对接触压力分布和接触力大小的影响,为解决夹持稳定性问题提供参考依据。The static mechanical properties between clamps and workpiece have been researched through numerical simulation.Serial factors which would influence the contact mechanical properties including the roundness and size of the work piece, friction coefficient of the contact interface, and the angle of clamps have been investigated, which provides reference for the solution of the stability in grasping.
