前几讲已经介绍了振动的危害及其防治方法,可以看出在很多情况下,振动是一种不必要的和有害的现象。但是在某些场合,通过对振动进行良好地组织和设计,能利用振动进行高效率的作业,有时其作业方式是用其它方式无法替代的,这时振动是有益的。这些利用振动的作业机械,称为“振动机械”。 In the last few weeks, the dangers of vibration and their prevention and control methods have been introduced. It can be seen that in many cases, vibration is an unnecessary and harmful phenomenon. However, in some cases, vibration can be efficiently arranged and designed through good organization and design of the vibration, and in some cases, the operation method is irreplaceable by other means. In this case, the vibration is beneficial. These working machines that use vibration are called “vibrating machines.”
