Gear Fault Diagnosis Method Based on the Integration of Empirical Mode Decomposition and Cepstrum Analysis
(0) Gear is the most common mechanical transmission equipment.Therefore,gear fault diagnosis is of much significance.In this article,a gear fault diagnosis method based on the integration of empirical mode decomposition and cepstrum is proposed by introducing empirical mode decomposition and cepstrum into gear fault analysis.Firstly EMD is used to decompose the gear vibration signal finite number of intrinsic mode functions and a residual error item.To do gear fault diagnosis,cepstrum analysis is carried upon those intrinsic mode functions to extract feature information from the vibration signal.The results of the study on simulated and experimental signals show that this method is better than the cepstrum method and it can precisely locate the site of gear failure.
