一、概述激振设备种类较多,其中电动振动台的应用比较广泛。电动振动台的激振原理,是将交变电流输入磁场中的线圈里,线圈就受到了交变力,驱动线圈框架(简称动圈架)产生往复振动。具有弹性负载的电动振动台的结构示意图,如图1所示。通电的动圈,在均匀的恒 First, an overview of more exciting types of equipment, including electric shaker more widely used. The vibration principle of the electric vibrating table is that the alternating current is input into the coil in the magnetic field, the coil is subjected to the alternating force, and the driving coil frame (referred to as the moving coil frame) generates reciprocating vibration. Schematic diagram of the structure of an electric shaker with elastic load, as shown in Figure 1. Power of the moving coil, the uniform constant
