本文提出一种用两只压电加速度计进行两次实验的互易校准方法,该方法可校准的频率范围从1kHz到8kHz,校准灵敏度的误差为±2.2％。还提出一种用三只压电加速度计进行六次实验的(不需要振动台激振)互易法校准,该方法可校准的频率范围从1kHz到5kHz,校准灵敏度误差为±5.3％。最后给出实验结果和旁证。 In this paper, we propose a reciprocity calibration method using two piezoelectric accelerometers for two experiments. The method can calibrate the frequency range from 1kHz to 8kHz and the calibration sensitivity error is ± 2.2%. A reciprocal reciprocal calibration with six piezo-accelerometers (no shaker excitation required) was also proposed, which calibrated a frequency range from 1 kHz to 5 kHz with a calibration sensitivity error of ± 5.3%. Finally, the experimental results and circumstantial evidence are given.
