4.3.3 An empirical study of vibration based bearing fault diagnosis methods

, , &
This paper presents an empirical study in which universally applicable fault diagnosis methods are used to evaluate vibration data of bearings. The data were acquired on two different test beds: a gear box test bed containing various bearings at different health states, and an accelerated life time (ALT) test bed to degrade a bearing and introduce an operational fault. Features are extracted from the raw data of two different accelerometers and used to monitor the...
