Analysis of a Rough Elliptic Bore Journal Bearing using Expectancy Model of Roughness Characterization
Journal Title: Tribology in Industry - Year 2014, Vol 36, Issue 2
Abstract
Performance characteristics of a rough elliptic bore journal bearing are studied. The bearing bore of isotropic roughness orientation is characterized by stochastic function and the film geometry is quantified to elliptic shape. There after the Reynolds equation and energy equation are descretized for pressure and temperature respectively. A finite difference model is developed to evaluate hydrodynamic pressure and oil temperature. Solution to this model is done using effective influence Newton-Raphson method. Performance parameters such as load bearing ability, friction, flow-in and side leakages are computed and discussed.
