摘要
本文基于检波器的理论模型,分别对加速度型与速度型检波器建立了检波器与大地的机电耦合动力学模型;设计完成了检波器地面耦合振动特性试验,试验数据拟合结果验证了模型的正确性,同时揭示了耦合共振频率与检波器附加质量、尾锥长度等参数之间的关系,研究工作为检波器的设计与使用提供了理论参考。
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.
