Abstract：When fault arises in rolling bearing the envelope demodulation analysis is the most commonly used method. However, when rolling element fault arises in rolling bearing the envelope demodulation analysis method could not extract the ball fault characteristic frequency perfectly due to the rolling elements’ contact with the outer race and inner race simultaneously. Besides, it is also influenced by the rotation of the cage. Taking advantage of the property of cyclostationarity when fault arises in rolling bearing, the paper proposes a fault diagnosis method of rolling bearing based on slice energy spectral correlation density (SESCD). The proposed method solves the above defect of envelope demodulation analysis in fault diagnosis of rolling element to some extent and has a degree of significance in fault diagnosis of rolling element.
