Review Of Machine Condition Monitoring Based On Vibration Data

In the process of channeling energy into job to be performed all machines vibrate. Machines rarely break down without some previous warning. The signs of impeding failure are generally present long before total machine breakdown. When faults begin to develop in the machine, some of dynamic processes in the machine are changed as well, thereby influencing machine vibration level, temporal and spectral vibration properties. Such changes can act as an indicator for early detection and identification of developing faults. This paper reviews the current position in machine condition monitoring based on vibration data analysis. After review of major, mature and well established approaches, new unsupervised approaches based on novelty detection are also presented.
