MODEL-BASED PROGNOSIS OF MACHINE HEALTH

摘要

A method and a system for providing a model-based machine health prognosis are disclosed. According to certain embodiments, the method includes obtaining one or more performance parameters of a machine. The method also includes determining whether cavitation occurs based on the one or more performance parameters. If cavitation occurs, the method further includes simulating, based on the one or more performance parameters, the occurrence of the cavitation using a computational fluid dynamics (CFD) model. The method further includes determining, based on output from the simulation of the cavitation, a remaining useful life of the machine using a finite element analysis (FEA).
