Extracting weak features of incipient bearing fault from the collected vibration of rotating system is the basis of the fault diagnostics of main bearing in the aero engine. To monitor the running condition of the main bearing, a novel weak feature extraction method for bearing fault, named as iterative squared envelope analysis (ISEA) is proposed by extracting the fault characteristic orders of bearings...
