锻压设备指的是锻锤和压力机(包括冲床),它们所产生的扰力形式各有不同。锻锤以锤头一定的下落速度作用,引起基础初速度而产生振动;压力机在公称压力作用下,机身立柱产生弹性伸长,当压力消失,主要由立柱变形恢复引起基础振动,至于传动部分引起的振动一般较小;这两种类型扰力均可近似为撞击性瞬态振源。锻锤打击时引起的振动能量很大,且传得很远。凡设有锻锤的车间、精密加工设备、精密仪器仪表、甚至办公人员和周围
Forging equipment refers to forging hammers and presses (including punches) that generate different forms of disturbance. The forging hammer acts at a certain falling speed of the hammerhead to cause the initial velocity of the foundation to cause vibration. Under the action of the nominal pressure, the press body is elastically elongated in the column of the fuselage. When the pressure disappears, the basic vibration is mainly caused by the deformation of the column. As for the transmission Partially induced vibration is generally small; both types of disturbances can be approximated as impinging transient sources. The vibration energy caused by the forging hammer striking is very large and it is transmitted very far. Where there are forging hammer workshops, precision processing equipment, precision instrumentation, and even office workers and around
