| Abstract: | The structure and operation principle of a double-sides tuning fork quartz vibrating beam gravity sensor was introduced.According to the formulas for the resonant frequencies of the quartz resonator and the piezoelectricity effect of quartz,the primary structural dimensions and electrode of the quartz resonator were obtained.Finite element method(FEM)analysis was applied to calculate resonant frequencies and display the first vibrating model.All these researches were helpful to design various quartz vibrating beam acceleration sensors. |
