Abstract

In LUBRICATION theories, the bearing surfaces are considered smooth, which is not really true. It has been shown in cases where the roughness is in the same order as the lubricant film that there would be a major effect in bearing performance. The surface geometry is so irregular that it is sometimes necessary to use statistical models. Usually, when we are faced with roughness effects, the analytical solution is very difficult. In this paper, FINITE ELEMENT method is used to examine the roughness effects on the performance parameters of step slider bearings. The problem was solved for two different surface profiles and the results were compared showing relatively close agreements.
