摘要

以一种适合在道碴等一类检波器难安置的场地使用的检波器尾座为例，通过导纳和模态试验分析理论对附加质量和接地刚度对传感器响应性能的影响进行了理论分析，将带尾座检波器应用于野外实地进行测试对比分析，表明了附加质量的和接地刚度对理想频带宽度的影响，试验结果与理论分析具有很好的一致性。证明了该种检波器尾座用于实际生产的可行性，说明了带该类尾座的检波器的本质特征。

Abstract

As a example of tailstock in seismic exploration, which is fit for those sites always difficult to install geophones by tail-cones such as the ballast site in railway, theoretic analysis is carried by the mobility and modal analysis theory. It shows the effects of the added quality and contact stiffness of the geophone response on the response characters in the frequency domain. The actual geophone has been used in model testing and field trials, from which the field tests is analyzed in contrast. The results are consistent with the theoretical analysis, which shows the influence on ideal bandwidth by added quality and contact stiffness. It has been proved that the tailstock detector is feasible in the real production. This essay also describes the essential characteristics of this kind of geophone with tailstock.
