基于轴承式杠杆机构的光纤光栅高频地震检波器设计
Design of fiber grating high-frequency seismometer based on bearing lever mechanism
摘要
Abstract
A fiber optic grating high-frequency seismic detector based on a bearing type lever mechanism is designed to address the relatively weak research on high-frequency signal waves at present.With the lever mechanism and bearing fulcrum as the in-novation point,the static structure analysis,modal analysis and harmonic response analysis of the detector model are carried out by using simulation software.The simulation results show that the simulation sensitivity of the geophone is 64.588 pm/g,and the simulation natural frequency is 1 638.5 Hz.By adjusting the length ratio between the power arm and the resistance arm of the lever amplification mechanism and the cutting radius of the cycloidal hinge,the simulation natural frequency of the detector is 1204.4 Hz and the simulation sensitivity is 75.56 pm/g.关键词
