摘要

通过分析涡流检波器的工作原理,建立起考虑检波器外壳影响下频响函数的7参数模型,将其与现有模型阻尼机理及影响因素比较.并设计了检波器参数识别实验系统,经过测试予以验证,为在检波器结构优化中控制其阻尼提供了理论依据.
Through analyzing the working principle of eddy geophone, this paper establishes seven parameter model of frequency response function considering the influence of geophone shell. Then the damp mechanism of seven parameter model are compared with the earlier model. The testing experiment system is designed to ascertain the geophone parameter. The experimental results evidences seven parameter model is effective in analyzing eddy acceleration geophone. And seven parameter model can be used in controlling the damp on optimizing geophone structure.
