Abstract

A model that treats both the EHL and the asperity contact friction in lubricated rough circular contact is presented in this article. In this approach, the well-known Greenwood and Williamson elastic contact model describing dry asperity contact is combined with an isothermal Eyring EHL model of the hydrodynamic film. It is shown that the friction results obtained from this approach are in good agreement with the experimental Stribeck curves measured on a ball-on-disc test rig.
