Condition Monitoring for Bearing using Envelope Spectrum of EEMD

摘要：

In order to overcome the shortcomings of the traditional envelope analysis in which manually specifying a resonant frequency band is required, a novel approach based on the ensemble empirical mode decomposition (EEMD) and envelope spectrum is proposed for detecting Localized defects in rolling bearings. This approach can extract the characteristic frequencies related to the defect from the resonant frequency band of the vibration signal. The techniques are demonstrated by the experiments on a machine tool with a bali bearing under simulated crack on the inner race or outer race. Experimental results show that the proposed approach is effective and reliable in detecting Localized defects of bearings.
