低速压机启动、寸动和冲裁工件时的扰力分析与振动计算

Calculation of the vibration exciting force and its response on a low-speed press when starting inching or punching

分析了机械压力机振动原因．对低速压力机启动，寸动和冲裁工件时的激振扰力和响应提出了计算方法，其结果可供机械压力机隔振设计参考。

The reasons are analysed for vibration of mechanical press and a newmethod is suggested for calculating the vibration exciting force and its response on a lowspeed mechanical press while starting, inching or punching. The conclusion drawn canbe used as a reference to press vibration isolation design.
