Abstract

An analysis based on a perturbation theory for evaluating the mass sensitivity, S/sub m/, for acoustic wave gravimetric sensors made of thin rods is presented. The lowest order flexural, F/sub 11/, torsional T/sub 01/ and longitudinal L/sub 01/ acoustic modes are of interest. The mass sensitivity is found to be -1/2 rho /sub s/a, -2/ rho /sub s/a, and -1/ rho /sub s/a for F/sub 11/, T/sub 01/, and L/sub 01/ mode, respectively.<>

细杆声波重力传感器分析

基于微扰理论，对细杆声波重力传感器的质量灵敏度S/sub - m/进行了分析。最低阶的弯曲，F/sub 11/，扭转T/sub 01/和纵向L/sub 01/声学模式是感兴趣的。对于F/sub 11/、T/sub 01/和L/sub 01/模式，质量灵敏度分别为-1/2 rho /sub s/a、-2/ rho /sub s/a和-1/ rho /sub s/a。
