| Abstract: | The fault diagnosis of rolling bearings is carried out by using discrete wavelet transform(DWT).The practical vibration speed signals measured from rolling bearings with faults are analyzed by the proposed methods,and the frequency spectrograms of fault signals are drawn respectively.The results show that the proposed methods are superior to the traditional methods in extracting the fault characteristics of inner ring and rolling element of rolling bearings. |
