Abstract
A method for predicting a remaining useful life of a bearing involves obtaining a plurality of sets of actual inspection data from the bearing. The method involves obtaining an estimated wear rate from a physics based model of the bearing. The method further involves adjusting the estimated wear rate based on the plurality of sets of actual inspection data to compute an actual wear rate. The method also involves computing a calibration parameter based on the actual wear rate. The method further involves predicting a remaining useful life of the bearing based on the calibration parameter.
