摘要
本文从孩电式绝对振动速度传感器的力学模型分析入手,采用模拟电子技术,对传感器的传递函数进行补偿、校正,将其等效固有频率降低到0.5Hz左右,从而实现对超低频绝对振动的测量。
Analyzing the mechanical model of magnet-electricaal Absolute Vibration Veloc-ity Transducer and adopting analogue electronic technology, the transfer function of transducer is compensated and rectified, its equivalent natural frequency is decreased to 0. 5Hz. Thereby the measurement of super low-frequency absolute vibration is reallzed.
