Fault Diagnosis of Rotating Machinery

This paper aims to provide a broad review of the state of the art in fault diagnosis techniques, with particular regard to rotating machinery. Fault diagnosis is a subject too wide ranging to allow a comprehensive coverage of all of the areas associated with this field to be undertaken, and it is not the authors' intention to do so. However, a general overview of the broader issues of fault diagnosis is provided, and several of the various methodologies are discussed. A detailed review of the subject of fault diagnosis in rotating machinery is then presented. Special treatment is given to the areas of mass unbalance, bowed shafts, and cracked shafts, these being among the most common rotor-dynamic faults. Vibration response measurements yield a great deal of information concerning any faults within a rotating machine, and many of the methods using this technique are reviewed.
