说明：  本文提出一种基于频率切片小波变换和谱峭度的综合算法。首先对轴承端的振动信号时频分析，采用FFT、包络谱、频率切片小波变换对其频域性能进行分析，再求其峭度谱与对应包络谱，结合其时域、频域性能，综合分析轴承故障。
(This paper presents a synthesis algorithm based on frequency slice wavelet transform and spectral kurtosis. Firstly, the time-frequency analysis of the vibration signal at the bearing end is analyzed. The frequency domain performance is analyzed by FFT, envelope spectrum and frequency slice wavelet transform. Then the kurtosis spectrum and the corresponding envelope spectrum are analyzed. Combining its time domain, frequency domain performance, Comprehensive analysis of bearing failure.)
