Survey of Diagnostic Techniques for Dynamic Components

Report No. ARL-TR-5082
Authors: Kwok F. Tom
Date/Pages: January 2010; 34 pages
Abstract: This survey summarizes some of the diagnostic techniques that have been developed for dynamic components such as bearings and gears. There has been a tremendous amount of research related to the detection of faults in these dynamic components over the past few decades. Typically, accelerometers are the main type of sensor used to obtain vibrational signatures of the component under evaluation. Application of signal processing techniques have been studied and evaluated as it relates to the improvement of the detection process for faults that are generated in dynamic components.
