Abstract :
Proposes a method for fault testing on a rolling bearing based on wavelet transformation and pattern recognition. Wavelet packets decomposition is used to extract features of dynamic vibration information; K-NN is introduced to test the fault on a rolling bearing. Experiments show that the proposed method attains a satisfactory effect.
