Research of the frequency calibration of high shock accelerometer using Hopkinson bar

Abstract

A method about the shock comparison frequency calibration is brought forward in this paper to calibrate a high shock accelerometer using the Hopkinson bar as the pulse exciter. The output of the standard accelerometer is used as the input of the test accelerometer, the output of the test accelerometer is used as the output of test accelerometer, the transfer function can be obtained by the characteristic of the input and the output of the test accelerometer, then the frequency characteristic of the test accelerometer is known.
