Equipment Fault Diagnosis Based on EMD and Wavelet Analysis
YIN Jia
Abstract：This paper presents a method of equipment fault diagnosis based on the combination of EMD and wavelet analysis. Firstly it processes the signal vibration data by EMD to get some IMF,and trying wavelet analysis for each IMF,then the most repre?sentative parts of the IMF are chosen through Hilbert transform,finally fault diagnosis is realized and researched by the HHT mar?ginal spectrum of IMF,so it can realize effective diagnosis and research for equipment failure. The experimental results show that the method based on EMD and wavelet analysis for equipment fault diagnosis is effective and feasible.
