摘要
HD—JSⅡ涡流检波器是一种涡流式加速度地震检波器,适用于所有地区的陆地地震勘探。本文利用振动力学理论,从检波器的结构和工作原理入手,提出了一种涡流检波器特性参数识别算法,可识别出检波器的固有频率、阻尼、灵敏度等特性参数,为涡流检波器参数综合测试仪研制提供了理论基础。
The HD-JS Ⅱ eddy geophone is a pattern of seismic geophone based on the operational principle of bow wave and acceleration, which is suit for the exploration of all regions. This paper proposes an arithmetic to identify the characteristic parameters of eddy geophone on basis of the vibration mechanics theory of the configuration of the geophone and its working principles. The arithmetic can identify the parameters of inherent frequency, damp, delicacy and so on. It also offers a theoretical base to the eddy geophone testing instrument.
