    小波分析由于具有同时分析信号时域和频域的特性,所以使用小波分析技术对检测的信号进行变换,然后对具有故障特性的信号进行重构,最后通过希尔伯特变换进行解调和细化频谱分析,从而轴承中的故障信息成分就可以检测出来,以判断轴承发成故障的部位。(Wavelet analysis has the characteristics of both time and frequency domain, so the wavelet analysis technique is used to transform the signal, then the signal is reconstructed. Finally, the fault information components of the bearing can be detected by Hilbert transform.)
