动圈式过阻尼地震检波器测试的研究

Research on the Measurement of Overdamped Coil Geophone

给出直流激励法测试动圈式过阻尼地震检波器的阻尼、自然频率和灵敏度等三个主要参数的原理和操作。

The principles and operations for the measurements of the main parameters of the overdamped coil geophone,such as damp,natural frequency and sensitivity,by means of AC excitation are described in this paper.Based on this theory,a kind of portable specific testing instruments has been developed.
