Application of structural health monitoring for damage identification in an industrial fan rotor using in-situ modal analysis testing
MetadataShow full item record
A testing procedure is desired which can be applied in manufacturing environments to determine the structural integrity of rotating components within a machine. Current non-destructive evaluation (NDE) of components includes visual inspection, dye penetrant, and x-ray testing. Each of these NDE techniques have limitations in manufacturing plants given very limited time frames and access to rotating components. Vibration condition monitoring is widely used and accepted as a beneficial way to determine faults in rotating equipment. Current vibration condition monitoring practices rely on ...
