摘要

本文首先介绍了在频率域上对爆破加速度测量系统的低频响应误差和高频响应误差的详细分析过程

并对输入、输出波形采用频谱分析及计算幅频曲线

用幅频曲线所包围的不同面积来计算经过测量系统后所引起的误差.其次介绍了采用傅里叶变换法如何在频率域上标定冲击加速度计

给出了确定加速度灵敏度的方法.

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.
