ANALYSIS OF SUSCEPTIBILITY OF CHARACTERISTIC FEATURES IN THE FAULT DIAGNOSIS OF GEARS AND BEARING

Pan Xufeng(Beijing Institute of Technology, Beijing, 100081)Geng Li'en Li Xiaolei(North Industries Economic Institute) (Beijing Institute of Technology)  
Feature extraction is one of the most important techniques in the fault disgnosis of mechanical systems. For the cases of gears and bearings, based on a variety of contrastive experirnents, 22 methods of feature extraction in the time and frequency domain are adopted in the paper, where acceleration signals collected in the experiment are analyzed. Difference in susceptibility of the features under various situations and fault conditions is compared. They are taken as the basis of decision in fault diagnosis.
