Abstract

A quartz resonator subjected to acceleration will deform due to inertial effects. The deformation stresses and strains in the plate will in turn cause a shift in the resonator frequencies. A method is proposed to actively minimize the inertial stresses and strains by a DC-bias electric field. Finite element models are created to calculate the effects of acceleration on resonant frequency and to compare the results with experimental data. The non-linearity and non-homogeneity induced by the inertial forces are modeled by using the concept of a superposed state. The model results for the acceleration effects are shown to compare well with the experimental results. The models are then used to calculate the effects of a DC electric field bias and to demonstrate the reduction of acceleration sensitivity.
