【摘要】 本文建立了全面反映压力机执行机构冲压过程各影响因素的动力学模型，利用该模型可以研究执行机构中各运动副的间隙、连接刚度、阻尼、执行机构的各参数，以及加载特性等对冲压过程的影响。文中对２５０ｋＮ开式压力机的实际冲裁过程进行了数值计算。更多还原

【Abstract】 A dynamic model to comprehensively describe the various factors of the stamping process of press executive mechanism was established.The model used enobles us to research on the clearance, connection stiffness,damping,every parameter of the exeutive mechanism and loading characteristic effect on the stamping process. Numerical calculation has been done for the practical blanking process of 250kN C-frame press.更多还原
