电磁振动器是工业中广泛应用的、最简单的定向起振器之一。可是电磁起振器的振动频率是50赫或100赫,而且振动的最大加速度由于弹性元件的强度而被分别限定为2.10~2和8.10~2米/秒~2。为了得到与上述不同的振动频率,不得不使振动器本身的结构或电源设备的结构(双轴惯性振动器、电动振动器、可控硅工业变频器等)复杂化。详细拟制的磁力机械起振器方案(苏联发明证书1018720)可以得到0～1000赫范围内定向振动的任何频率,且振动频率超过150赫时其加速度可达(1～5)·10~3米/秒~2。
Electromagnetic vibrators are one of the most widely used and easiest directional exciters in the industry. However, the vibration frequency of the electromagnetic vibrator is 50 Hz or 100 Hz, and the maximum acceleration of vibration is limited to 2.10 to 2 and 8.10 to 2 m / s to 2, respectively, due to the strength of the elastic member. In order to obtain a different vibration frequency from the above, the structure of the vibrator itself or the structure of the power supply device (dual-axis inertial vibrator, electric vibrator, thyristor inverter, etc.) has to be complicated. The detailed and elaborated magnetic mechanical vibration exciter scheme (Soviet Union invention certificate 1018720) can obtain any frequency of directional vibration in the range of 0-1000 Hz and acceleration up to (1-5) 10-3 at vibration frequency over 150 Hz M / s ~ 2.
