小波变换在故障诊断中的应用

Application of wavelet transforms on fault diagnosis

小波变换是一种日益获得广泛应用的信号分析方法。介绍了小波变换基本原理和利用小波变化来检测信号的奇异特征的原理,证实了小波变化在检测奇异信号方面的有效性。结果表明基于小波变换的去噪方法是非常有效的。

Wavelet transform is a kind of method that being widely applied in signal analysisThis paper introduces the principle of wavelet transform and the theory based on wavelet transform in detecting strange of signal is studiedCase study shows that wavelet transform is effective on detecting strange featureThe result shows that the method of elimination no noise by wavelet transform is very effective
