对原始滚动轴承的时域信号进行傅里叶变换,然后进行二次频谱变换即倒频谱分析.得出的结果能较好地反映出周期信号中的突变.通过对轴承内圈外圈的实验信号进行分析,结果表明,该信号分析方法能对轴承的大部分故障情况有效地监测.
The time-domain signal of the original rolling bearing is Fourier transformed, and then the second spectrum transform, ie cepstral spectrum analysis, is obtained.The results can well reflect the sudden change in the periodic signal.By the experimental signal The results show that the signal analysis method can effectively monitor most of the bearing failure.
