Effect of different textured surfaces on lubricating characteristics of area contact friction pairs

Abstract

A theoretical analysis model was developed for area contact friction pairs with different micro- Textures considering cavitation within the fluid film between two faces. Numerical simulation method was used to study the effect of geometric parameters of different micro- Textures on the load carrying capacity and the friction coefficient. Results show that hydrodynamic lubrication problem of textured surfaces has been solved with a single-dimple model and a multi-dimple model. The tendency of the multi-dimple solutions is similar to that of the single dimple model, but the magnitudes of load capacity and friction coefficient are different. © Springer-Verlag Berlin Heidelberg 2010.
