Intelligent bearing fault signature extraction via iterative oscillatory behavior based signal decomposition (IOBSD)
作者:
Highlights:
• A method based on oscillatory behaviors is proposed for bearing fault detection.
• The IOBSD is developed for handling signals with multiple interferences.
• The strategies of Q-factor determination and tuning for TQWT are exploited.
• The proposed method can remove in-band interferences and noise.
• The proposed method requires neither prior signal knowledge nor prefiltering.
