Tribological Phenomenon for Advanced Diesel Engines - Engine Modeling

"This proposal comprises research efforts to study a dynamic non-stationary friction regime with a variable range of external factors or parameters. This research method considers the development of special non-linear mathematical models for enginetribology including the lubricating oil film thickness as a function of a series of independent parameters in extreme working conditons. These models are proposed to be used collectively to model an advanced military diesel engine. This "whole" enginemodel will be flexible enough to allow incorporation of other bearing, ring pack, parasitic component or other tribology phenomenon source. Each individual tribo-phenomenon source will be varified by laboratory bench test rig and in a future effort, on afull scale advanced military diesel engine. The Phase I effort serves to verify this modeling concept. The Phase I Option serves to optimize and examine methods of incorporating these model into a "whole" complete engine model. This in turn will serveas an analytical tool not only to assess tribological phenomenon, but also to predict or project their effects on powerplant performance. Future work would incorporate this model into an easy to use 3-dimensional user interactive interface model.Prediction of the effect tribological events place on overall engine performance have been an area of interest for virtually all operational powerplants. The effect of friction and wear is critical t
