摘要

本文采用有限元法分析了二维石英石板的激励模态和死模态。首先用平面应变简化法对三维石英板进行简化，然后将简化后的三维石英板与二维石英板的模态进行比较。然后分析了at切割板和sc切割板的石英振动元件。为了了解受电压载荷激励的石英板共振频率的规律，我们将石英板的固有振动与受电压载荷激励后产生的激励频率进行了比较。

Analysis of Excitation and Dead Vibration Modes of Quartz Resonators

This study uses the finite element method (FEM) to analyze the excitation and dead vibration modes of two-dimensional quartz plates. We first simplify three-dimensional quartz plates with plane strain simplification and then compare the modes of the simplified three-dimensional plates to those of two-dimensional plates. We then analyze quartz vibrating elements of AT-cut plates and SC-cut plates. To understand the regularity of the resonance frequency of plates that are excitable by voltage loading, we compare the natural vibrations of quartz plates with the excitation frequency generated after the plates are excited by voltage loading.
