Research Progress of Application of Empirical Mode Decomposition in Fault Diagnosis

With the deepening research in the field of mechanical vibration, empirical mode decomposition (EMD) is more and more used in the extraction and intelligent recognition of mechanical fault features. This article reviews the research results and development trends of domestic and foreign scholars using EMD in recent years. It mainly includes the basic principles of empirical mode decomposition, and the application of it in fault feature extraction, intelligent recognition and the latest progress. This article also systematically summarizes the application of EMD in mechanical fault feature extraction and fault identification, which provides a theoretical basis for mechanical fault diagnosis in actual working conditions, proposes related problems to be solved when using EMD to diagnose mechanical faults and prospects for future development trends.
