摘要
高频谱峰群中含有轴承故障的信息，采用二次FFT分析法对高频谱蜂群进行分析，能成功地诊断出产生疲劳剥落的轴承元件。
A group of peaks at the high frequency rcgion of a spectrum of a bearing vibration signal contains fault information of the bearing. An exact diagnosis of the bearing elements with fatigue pittings can be made by a further Fourier transform of the group of the spectral peaks.
