Abstract:
Based on mechanics of vibration, the resonant differential equation of resonator is derived, and the design principle is discussed for the vibrating beam accelerometer. Extracting the characteristic parameter from resonance accelerometer, the structure is optimized and the non-linear error is analyzed. According to the piezoelectricity effect of quartz, the encouraging way, shear selection and electrode configuration are analyzed and discussed. The analyses of its modes and force-frequency characteristic are implemented by the finite element analysis tool. The difference of force-frequency factor between simulation results and calculated results are less than 4 percent and the theoretic models are proved to be correct and reliable. All these researches are helpful to design high precision accelerometer.
