Abstract

In order to better identify the fault type of locomotive running of rolling bearings, through experiment and analysis, the article improves a new method by combining the value of AdB and fault bearing fault characteristic frequency, then through the virtual instrument software to analysis the diagnosis method. Firstly, the extracted data are filtered by two-dimensional Gabor band-pass filter, and then the cepstrum analysis is performed on the filtered data. Through the analysis of the characteristic information, the fault frequency can be obtained, and the fault range is given according to the inherent characteristic frequency of the rolling bearing, and then the final fault level is given by calculating the AdB value. This method can give more accurate fault types and give warning signs in advance, which greatly improves the safety of the locomotive.
