介绍了一种自校准压电加速度计，即在其内部设计二组元件，一组为驱动元件、一组为敏感元件。驱动元件在外加电压作用下对敏感元件产生激励信号，压电加速度计因此输出电信号，我们将此参数叫自校准系数。在实际校准时，检测自校准系数是否改变来判断该加速度计性能是否改变，分析了影响自校准系数的因素，提出了改善自校准系数的几项措施，探讨了自校准功能的增加对压电加速度计测振参数的影响。
A self-calibrating piezoelectric accelerometer is introduced, that is, two sets of elements are designed in the interior, one is the driving element and the other is the sensitive element. The driving element generates an excitation signal to the sensing element under the action of an applied voltage, and the piezoelectric accelerometer outputs the electric signal, and we call this parameter a self-calibration coefficient. In the actual calibration, the self-calibration coefficient is detected to determine whether the accelerometer performance changes. The factors that affect the self-calibration coefficient are analyzed. Several measures to improve the self-calibration coefficient are proposed. The effects of the self-calibration function on the piezoelectricity Influence of accelerometer vibration measurement parameters.
