对动圈式恒速度型过阻尼地震检波器相对阻尼系数的测量方法进行了研究。
It was devoted to the relative damping measurement for overdamped geophone with a moving coil of constant velocity.
根据该方法，相对过阻尼系数能够表示成检波器响应曲线的半峰高宽度和检波器自然频率乘积的线性函数。
According to the method, the relative overdamping can be expressed in a linear function of the product of the width of half peak of the response curve by the nature frequency of the geophone.
结论是在模态对模型下，冲击力增大时，模态距离呈增大趋势，而地震检波器的阻尼趋于稳定。
It is demonstrated with mode-pair model that as the impact force become larger, the mode distance tend to increase, and the damping tend to stability.
采用加速度检波器芯体、增大速度检波器芯体阻尼等措施，可改善二次谐振的危害，经实际应用效果较好。
The harm of the secondary resonance could be improved by the measures such as using the acceleration detector core body, increasing the damp of velocity detector core body and so on.
