摘　　要：应用Deform商业有限元分析软件,对不同厚度的板料冲裁过程进行模拟计算,获得冲裁过程各阶段应力、应变状态,以及整个过程冲裁力的变化。分析了冲裁工艺参数对板料裂纹生成及板料断裂位置的影响。从而可以根据冲裁过程中材料的应力应变与滑块速度的关系来制定冲裁工艺,编制冲裁力-行程曲线,使得冲裁力变化缓慢,延长贮存在压力机的弹性变形能的释放时间,以大大降低机器的振动与噪声,最终达到静音冲裁的目的。Deform is used to simulate blanking process of sheet metal with different thickness. The result of stress and strain distribution,blanking parameters＇ effects on the crack and the force-stroke curve of the entire blanking process. According to the relationship of stress-strain and slide velocity in the blanking, blanking process and blanking force-distance curve is made. So the blanking force changes slowly and the release time of elastic deformation energy stored in the press machine is extended. And then the noise and vibration of the machine is greatly reduced, so as to achieve the purpose of mute blanking.
