摘要

采用激波管实验装置对不同长度、不同直径的引压管进行了实验.利用MATLAB编写了快速傅里叶变换(Fast Fourier Transform

FFT)算法

通过FFT算法计算了实验结果的频率特性

分析了长度、直径对引压管动态特性的影响.结果表明:随着直径的增加

引压管的工作频带变宽;长度是最主要的影响因素

直接决定引压管的工作频带

长度越短其工作频带越宽.

Abstract

A series of experiments on transmission tubes with different lengths and diameters were carried out.Fast Fourier Transform(FFT) algorithm was compiled with MATLAB

and the frequency characteristics of experimental results were analyzed by the algorithm to revealed the influences of length and diameter on the dynamic characteristic of the transmission tubes.The results showed that the working frequency band of transmission tube becomes broad as the diameter increases and it also becomes broad as the length decreases.
