dc.description.abstractOscillatory Behavior-based Signal Decomposition (OBSD) is a new technique which decomposes a signal according to oscillatory behavior, instead of frequency bands. It has been used for bearing fault signature extraction under constant speed conditions, where the bearing fault-induced vibration signal can be regarded as a low oscillatory component and the interference can be regarded as a high oscillatory component. However, its effectiveness for bearing fault signature extraction under time-varying speed conditions has not been evaluated. Theoretically, the OBSD is a frequency-independent method and should thus be effective under time-varying speed conditions. In this paper, the performance of the OBSD for bearing fault signature extraction under time-varying speed conditions is examined. The results show that the OBSD can be effectively utilized to extract the bearing fault signature under time-varying speed conditions.
