Research on geophone coupling mechanism

Li Peichao,Sheng Guotai,Xie Shilin and Guo Biao.  
The electro-mechanical dynamic models of geophone-ground coupling for velocity type and acceleration type geophones are established respectively upon the theoretical models of geophones.In addition,geophone-ground coupling experiments are carried out.The test data fitting results verify the accuracy of the built model and reveal the relationship between geophone-ground coupling resonance frequency and geophone parameters such as additional quality,tail cone length and so on.The work provides a theoretical reference for design and application of geophones.
