Abstract: Embodiments disclosed herein may include methods, systems, and tangible, non-transient, computer-readable media having instructions thereupon for determining a damage state of a wind turbine gearbox. A method performed, executed on a processor of a system, or implemented by a processor as instructions, may comprise producing a damage state diagnostic, producing a damage progression model for the wind turbine gearbox using operational data and a state transition function, and combining the damage state diagnostic with the damage progression model using a hybrid prognostics model to produce a probability distribution of a current damage state estimate. Producing the damage state diagnostic may comprise obtaining a measurement dataset for the wind turbine gearbox, integrating field-operator-provided intelligence into the measurement dataset, normalizing the measurement dataset with respect to a known failure behavior for the wind turbine gearbox, and combining the normalized measurement dataset with the known failure behavior to produce the damage state diagnostic.

Abstract: A system and method of additive manufacturing is disclosed herein which when run or performed form a product with a powder-based additive manufacturing device by adding sequential layers of material on top of one another. As each sequential layer of material is added, the system and method can include monitoring the sequential layer with a defect analysis subsystem to detect whether the sequential layer has any defects. For a detected defect, it can be determined whether defect correction is required. For a required defect correction, one or more correction parameters for the required defect correction can be identified; and a correction command including the one or more correction parameters can be sent to the additive manufacturing device, the correction command causing the additive manufacturing device to help correct the detected defect in the sequential layer according to the correction parameters prior to moving on to a next sequential layer.

Abstract: A system and method for determining surface contact fatigue life may use a finite element method to determine when components, such as a power transmission component, may fail in operation. The method may generate a finite element model based on the material parameters related to a power transmission component, generate a surface pressure time history for a loading event based on one or more loading parameters, determine, based on the surface pressure time history for a loading event, a finite element solution that describes stress in the grain structure, calculate damage in the finite element solution using a damage model, and determine whether a damage threshold is exceeded.

Abstract: A system and method is disclosed for predicting and comparing wear scenarios in a rail system. The method can include generating and running a contact model of the interaction between a rail and a train car to produce a simulated loading on the rail for a predetermined time period; generating and running a wear model based on the material properties and/or friction modifier properties of the rail using the simulated loading to produce a simulated wear profile of the rail for the predetermined time period; obtaining a grinding profile to be performed on the rail during the predetermined time period; and generating an updated rail profile by modifying the rail profile by the simulated wear profile and the grinding profile. The method can predict and compare crack growth over time, and provide a financial model and comparison of costs and benefits for different maintenance protocols for the rail system.

Abstract: A system for determining a health state of a component includes a processor and a non-transitory computer-readable storage medium that stores a plurality of computer-executable instructions thereon. The processor, in response to executing the plurality of computer-readable instructions, may be configured to perform one or more steps. The steps may include obtaining, from a first data source, usage data for the component; obtaining, from a second data source, a condition indicator for the component; running a usage model to produce usage parameters for the component based on the usage data; running a damage model to produce a damage estimate for the component based on the usage parameters; and running a prediction model to produce a health state estimate of the component based on the damage estimate and the condition indicator.
