| Abstract: | 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. |
