Abstract： Based on the analysis of the reflecting laser Doppler principle, the method for the chock calibration of high-g piezoresistive accelerometer was studied in this paper. The Hopkinson bar was used to generate an excited acceleration pulse which is absolutely measured using the differential laser interferometer. A set of calibration experiments was conducted for the accelerometer SIMIT-AYZ-60k. The shock sensitivity of the accelerometer was calculated from the quasi-dynamic data using the least squares method. It is demonstrated that this method is available for the calibration of the high-g accelerometers whose characteristic frequencies are different using the exciting pulse with the definite duration. The calibration accuracy is adequate to the engineering measurement.
