Fault diagnosis for gearbox based on EMD and multifractal
Ling Zhao, Xiaoyan Chu, Huang Darong · 2014
The application of the multifractal theory in gearbox fault diagnosis has been studied in the paper, and the fractal characteristics of gearbox vibration signals is shown. Based on using EMD, the improved algorithm of multifractal spectrum is put forward, and is applying to extract the fault feature. At last, the fault diagnosis application in gear box takes as the example to prove the feasibility of the method.
