| Abstract: | This paper analyses in detail the error of high and low frequency responses for measuring eplosion acceleration system in the frequency domain.
The error caused by measuring system is calculated by means of spectrum analysis of input and output waveforms and different areas enclosed by amplitude-frequency curves. In addition, this paper introduces a method of calibrating impulse accelerometer in the frequency domain by Fourier transform method and presents a formula to determine the sensitivity of accelerometer. |
