Abstract: The conventional calibration methods for shock accelerometers include the absolute, relative and comparative methods. A new calibration method, analogy comparison was proposed by synthesizing the advantages of the relative method and the comparison method. In the calibration by applying the proposed analogy comparison method, the standard accelerometer can be traced to the national benchmark by using the absolute method, and based on the measured shock force and dynamic strain, the sensitivity, amplitude linearity and frequency response of the measured accelerometer can be calibrated by exchanging the measured accelerometer with the standard accelerometer in the same shock condition. Thereby, the influences of the measured shock force and dynamic strain on the accelerometer calibration can be weakened and the shock accelerometer can be accurately calibrated.
