An Electrical Conductance Equation for the Piezoelectric Accelerometer and Its Application

本文推导出描述压电加速度计电端口特性的数学模型——电导纳方程,基于此方程,对校准压电加速度计共振频率的电容法给予了严密的解释,并设计了一种新的电容法实现方案。实验结果与理论上的结论是一致的。

In this paper,an electrical conductance equation for the piezoelectric accelerometer,which is the theoretical hase for calibrating the resonance frequency of piezoelectric accelerometer by using capacitance method,is derived.Based on this equation,a new design of capacitance method is introduced.The experiment results are coincident with the theoretical predictions.
