Shock Calibration of High-g Accelerometers with a Width Excitation Pulse
In order to determine the duration of shock pulse used as an excitation in the absolute calibration of high-g accelerometer, a calibration principle was put forward based on mathematical model of accelerometer. For the accelerometers with different natural frequency, the principle presented the relationship of the first order natural frequency and damp of accelerometer, calibration error and the least excitation pulse duration. With a Hopkinson calibration system, the correctness of the principle was validated by calibration experiments for a high-g accelerometer 988 and SIMIT-AYZ-3. This principle has provided the theoretical basis for the determination of the shock pulse duration in the absolute calibration.
