摘要
提出了利用磁电式速度计实现超低频振动传感器的实用方法 ,通过串联式校正电路 ,在保持最佳阻尼的同时 ,使可测最低频率降至 0 .5Hz以下。对该超低频振动传感器的校正电路、工作原理。
This paper puts forward the practical methord of realizing ultra low frequency vibration sensor by means of magnetoelectric speedometer,through the series type correcting circuit,the measurable minimum frequency is reduced to less than 0.5Hz while the optimal damping is keeped.The systematic analysis on the correcting circuit,working principle,transfer function and differences of the output characteristic before and after correcting of ultra low frequency vibration sensor is carried out.
