Research abstract
Current gearbox life estimation techniques commonly underplay the significance of gear tooth surface fatigue due to the complexity of the phenomenon involved. The Phase I program successfully demonstrated the feasibility of utilizing advanced modeling techniques to predict the onset and propagation of surface and bending fatigue in spiral bevel gears, including an analysis of mixed-elastohydrodynamic lubrication and damage accumulation in the material. Phase II will build on this success by developing these models into a complete gear life analysis, including a comprehensive graphical user interface for model construction and analysis control. Extensive verification of the models will ensure accuracy of the results. The completed software will provide analysts with a tool to predict the life of helicopter spiral bevel gears.
