摘要
为了实现地震波的三维采集, 设计了一种三分量光纤布喇格光栅(FBG)地震检波器, 理论推导了该检波器的固有频率和灵敏度, 先后使用Matlab软件、COMSOL软件对检波器进行结构参数优化和模态分析, 测试了检波器的幅频响应、横向抗干扰性能和灵敏度响应。实验结果表明: 检波器的平坦区为0.6~50 Hz;一阶、二阶和三阶的固有频率分别为56 Hz、59 Hz和63 Hz, x、y和z方向上灵敏度分别为218.22 pm/g、284.76 pm/g和249.67 pm/g;每个方向上的横向抗干扰度均小于5 %, 可实现低频信号的三分量检测。
Abstract
In order to achive three-dimensional seismic wave, a three component fiber Bragg grating(FBG) geophone is designed, and the natural frequency and sensitivity of the seismometer are theoretically deduced. Matlab software and COMSOL software are used to optimize the structure parameters and analyze the modal of the seismometer. The amplitude-frequency response, transverse anti-interference performance and sensitivity response of the geophone are tested. The experimental results show that the flat region of geophone is 0.6~50 Hz. The natural frequencies of the first, second and third order are 56 Hz, 59 Hz and 63 Hz, and the sensitivities in x, y and z directions are 218.22 pm/g, 284.76 pm/g and 249.67 pm/g, respectively. The transverse anti-interference degree in each direction is less than 5%, and the three component detection of low-frequency signal can be realized.
