In order to extract useful features from axle box vibration signals, an exact feature extraction method using the frequency slice wavelet transform (FSWT) is presented. Firstly, the vibration signal is decomposed with the FSWT and the full band of its time-frequency distribution is obtained. After that, time and frequency intervals are chosen to get zoom(More)
In order to extract the features of wheel-rail vibration, a novel fault diagnosis approach using time-frequency slice analysis is proposed. Firstly, wheel-rail vibration signal was transformed by frequency sliced wavelet transform (FSWT) to get the time-frequency characteristic figures of wheel-rail impact. Secondly, the time-frequency region was selected(More)
