电动振动台的工作原理与永磁式电动相声器的基本工作原理一样。它们都是根据在磁场中的通电线圈受到一个使线圈运动的力作用原理设计的,其结构主要由一个弹性悬挂的运动圈(以下简称动圈),和一个磁路结构组成。激振设备最初是因航空事业的兴起而出现的。当时的激振器只是一种十分专用的设备。随着航空和宇航事业的发展,激振设备由推力很小的激振器已发展到现在的推力达几十吨的振动台,工作频带的上限由500赫
The working principle of electric shaker is the same as the basic working principle of permanent magnet type electric math. They are based on the principle that the energized coil in a magnetic field is subjected to a force that causes the coil to move. The structure is mainly composed of an elastically suspended moving coil (hereinafter referred to as a moving coil) and a magnetic circuit structure. Excitation equipment was originally due to the rise of aviation. Exciter was only a very special equipment. With the development of aerospace and aerospace industries, the exciting equipment has been developed from the small-thrust exciter to the present-day shaking table with tens of tons of thrust. The upper limit of the working frequency band is 500 Hz
