摘　　要：介绍振动激励法和冲击激励法校准压电加速度计的工作原理,通过对压电加速度计灵敏度的校准试验比较两种校准方法的测试结果,并对测试结果的异同进行分析。试验结果表明,在压电加速度计允许使用频率范围内,两种校准方法的校准结果具有较好的一致性。本研究对选择合适的压电加速度计校准方法具有一定的借鉴作用。The principles of vibration excitation method and shock excitation method for piezoelectric accelerometer calibration are introduced. Through calibration experiments for the sensitivity reponse rate of piezoelectric accelerometer, the calibration results of two methods are compared, and the similarities and differences of which are analyzed. The experimental results verified that calibration results of two methods have good consistency within the allowed frequency range of piezoelectric accelerometer. The research possesses certain reference meaning to the choice of suitable calibration methods for piezoelectric accelerometers.
