摘　　要：在板材剪切加工过程中,影响剪切力的因素很多。文中主要从剪刃的几何形状对剪切力的影响进行研究分析。基于塑性有限元法对板材加工过程进行有限元分析,得出了板材的剪切力行程曲线,通过对曲线的分析,获得剪刃为一弧形刃一平行刃这种组合方式的合理性与可行性。There are many shear force factors in the sheet metal processing.The paper discusses the impact of the cutting edge geometry to the shear force.Based on the rigid-plastic finite element method,finite element analysis for the board processing is carried out,and stroke curve is obtained.Through the curve analysis,the combination of a curved and parallel blade edge to the edge is rational and Feasible.

关 键 词：剪刃形状 剪切力 刚塑性有限元法
