Abstract:

Gear tooth surface fatigue (pitting) is common precursor failure mode that leads to excessive gear vibration, liberation of debris particles that damage ancillary components (e.g. bearings), and serves as crack initiation sites that lead to eventual catastrophic tooth failure. Current gearbox life estimation techniques commonly underplay the significance of gear tooth surface fatigue due to the complexity of the phenomenon involved. In this Phase I program, technologies necessary for rigorous inclusion of surface fatigue failure will be developed to provide a better estimation of gearbox life for a given set of experienced (past) and anticipated (future) mission profiles. Finite element analysis will be coupled with a detailed mixed-elastohydrodynamic lubrication model and continuum damage mechanics approaches to predict damage accumulation rates in the material microstructure. Estimations of dynamic loading will be obtained through lumped-parameter analysis of the gearbox system. The completed software will provide analysts with a tool to predict the current damage state in helicopter gearboxes and evaluate remaining useful life for anticipated mission profiles.
