RESEARCH ON FAULT DIAGNOSIS METHOD OF ROLLING BEAR BASED ON SYMBOLIC ANALYSIS OF INTRINSIC MODE FUNCTION

A fault diagnosis method of the intrinsic mode components symbolic analysis is proposed on the basis of empirical mode decomposition. Firstly,the extension fault signal is decomposed into several intrinsic mode functions under different time scales with empirical mode decomposition. Secondly,analyze...
