A series of relative comparison studies of textured surfaces was carried out for a lubricated concentrated contact. The textures were numerically generated and the evaluation of the textures was based on a mixed EHL model. An effective viscosity was introduced to describe the non-Newtonian lubricant properties, which may be a function of the shear stress and pressure. Lubricant density may vary as a function of pressure and may be treated by the Dowson-Higgingsen formula. The fabricated texture shapes may deviate from the numerically suggested geometry due to practical tooling design or elastic restoration. Rougher machined surface may reduce the film thickness enhancement effect of dimples. This is an abstract of a paper presented at the World Tribology Congress (Kyoto, Japan 9/6-11/2009).
