Wavelet Transform Applied in Bearing Fault Diagnosis |
| |
| Abstract: | Wavelet transform theory was applied to deal with the problem of the non-stationary signal feature extraction in the bearing fault diagnosis.The test bed of bearing fault experiment was constructed,and a lot of experimental data was collected.After the typical fault experiment of the rolling element pitting and data treatment using wavelet transform,the fault characteristic frequency parameters were obtained,which verified the effectiveness of the wavelet transform used in non stationary signal treatment. |
