Since the bearing impact faults exhibit the non-stationary characteristics, the diagnostic method of time-frequency distribution is perhaps possessed of advantage. Based on Wigner-Ville cross-term distribution properties of amplitude modulation signal, this paper presents an approach of cross-terms false spectral energy to diagnose machinery faults, and the transmission band core function was designed to extract the cross-terms false spectral energy. Finally, the impact experimental data of bearing was given to show the approach availability. [ABSTRACT FROM AUTHOR] |
