小波分析在故障监测及诊断中的应用

摘要

The properties of wavelet transform in dyadic scales are studied. The principle that the module maximum value of wavelet transform of signal stands for the singularities of signal is discussed. Finally, this method is applied to an engineering example and the results are also given in this paper.%简要分析了小波变换的二尺度特性，对小波变换模极大值表征信号奇异性的原理进行了讨论，并给出了它在故障监测及诊断中应用的实现方法和实验结果.
