Traction Modeling of Military Oils

Abstract

A semi-empirical approach to modeling the traction behavior of turbine engine lubricants in concentrated contacts is presented. Coefficients for the model are determined by carrying out a nonlinear least-square analysis of available traction data. The effectiveness of the modeling approach is demonstrated by incorporating the lubricant traction model in a bearing dynamics computer code and by carrying out bearing performance simulations as a function of the coefficients of the traction model. Keywords: Traction, Lubricant Modeling, Elastohydrodynamic, Lubrication, Rolling Element Bearings, oils.
