摘　　要：应用DEFORM软件对双偏心曲柄摆剪的剪切过程进行有限元仿真。着重考察剪切参数(包括剪刃间隙、剪刃平段宽度、磨损状态以及剪刃形状)对剪切力、剪切断面质量的影响。研究结果表明:模拟仿真得到的剪切力与理论计算值相差6%,并得到了剪切力、剪切断面质量随剪刃参数变化的规律。这可以指导合理的设置剪切参数,为摆剪的实际使用提供理论支持。An FE simulation study for shearing process of couple off-center flying shear was done by using DEFORM. Focus was given on the influence of shearing parameters（ including shear blade clearance,flat section width of shear blade,the wear state and shear blade shape） on the shear force and quality of shear section. The results show that the simulation of the shear stress and the theoretical calculation of the difference is between 6%,and the shear force,shear sectional quality change rule with parameters of shear blade are obtained. This can guide setting shear parameters reasonably and provide theory support for couple off-center flying shear in actual use.
