计算分析了曲柄压力机运动时曲柄滑块系统产生的惯性力以及冲裁过程中卸载时弹性变形能的释放两者所引起的振动；指出在曲柄压力机下加聚氨酯垫，可以大大减小机床的振动．
The vibration caused by the crankshaft slider system inertia force and the release of elastic deformation energy during unloading are analyzed and calculated. It is pointed out that adding polyurethane pad under the crank press can greatly reduce the machine tool The vibration.
