Feature extraction of the weak periodic signal of rolling element bearing’ early fault based on shift invariant sparse coding
When fault such as pit failure arises in the rolling element bearing the vibration signal of which will take on periodic characteristics, and the abrupt failure of rotating machinery can be avoided effectively if the weak periodic characteristics of the early fault stage is extracted timely. However...
