Publication number: 20200409349Abstract: 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.Type: ApplicationFiled: June 17, 2016Publication date: December 31, 2020Inventors: Rahul Srinivas PRABHU, Hombe GOWDA, Souvik MATH, Venkatesh Kattigari MADYASTHA

Patent number: 10876927Abstract: A method (60, 90) includes executing a wear protocol to derive a start-stop (SS) wear, a steady-state operating hours (OH) wear, or a combination thereof, of a test journal bearing system (10). The method (60, 90) further includes observing operations of an engine (8) via one or more sensors to determine a number of start-stops, steady-state operating hours, or a combination thereof. The method (60, 90) also includes determining a determined journal bearing system wear (114) based on applying a physics-based model (94) of a journal bearing system (10) and the transfer function to the number of start-stops, the steady-state operating hours, or to the combination thereof. The method (60, 90) additionally includes executing one or more actionable items (116) on the engine (8) based on the determined journal bearing system wear (114).Type: GrantFiled: November 30, 2016Date of Patent: December 29, 2020Assignee: AI ALPINE US BIDCO INCInventors: Souvik Math, Hombe Gowda, Krishnanand Venkatasubramanian
