摘要
论述了小波包分解及其能量谱处理超越离合器故障的原理与方法。应用小波包分解及其能量谱直观地识别出故障的特征频带 ,并进行了量化分析。结果表明 ,小波包及小波包分解能量谱比传统的傅里叶分析方法具有更大的优越性及实用价值。
The theory and method of wavelet packet decomposition and is energy spectrum dealing with the fault of the overrunning clutch are presented in the paper.The characteristic frequency band of the fault can be identified by wavelet packet decomposition and its energy spectrum conveniently,and the quantification analysis are then performed.The results show that this method is of practical value and more advantageous than traditional Fourier analysis method.
