Fault Diagnosis of Rolling Bearings Based on Hilbert Resonance Demodulation Method

Abstract

Rolling bearings play the role of transmitting power and bearing loads. In the event of failure, not only the failure modes are different, but also the vibration signal characteristics are different. Based on the analysis of the failure mechanism of rolling bearings, the application of Hilbert resonance demodulation method in the typical fault diagnosis of rolling bearings is verified by specific experiments, which provides an important reference for the accurate diagnosis of rolling bearing faults.
