Abstract: As part of the U.S. Army Research Laboratory (ARL) Prognostics and Diagnostics (P&D) Program, a series of experiments were performed to study defects in ball bearings. The P&D Program objective is to develop and implement algorithms that detect and classify faults in U.S. Army systems, providing information on the state of health and predictions of remaining life. Due to the substantial use of bearings in Army assets and the significant impact of improving health assessment of bearings in operation, they were selected for a focused study, with the additional goal that any algorithms/methodologies gained by performing research on them would likely have application in other fields of health assessment. The goal of the work described here was to collect sufficient data on healthy and a variety of faulted ball bearings for evaluation of various analysis techniques.
