The Application of EEMD to Fault Diagnosis of Rolling Bearing

Abstract:

The EEDM(Ensemle Empirical Mode Decomposition) combined with correlation coefficient was proposed for identify the fault of rolling bearing. First, the fault of rolling bearing vibration signal will be decomposed into several IMF components, in view of the illusive component may appear in EEDM components, respectively calculate each IMF components and the correlation between the original signal, then carry out spectrum analysis to each IMF components and pick up fault feature. Through the experimental failure data analysis of rolling bearing inner ring, the EEMD method is good for fault identification of rolling bearing.
