Abstract
A simplified method for numerical calculation of the traction in partial elastohydrodynamic lubrication (EHL) was proposed. There was a clear difference between the calculated results of the rheology model and the experimental results in partial EHL, the rheology model is an effective method for numerical calculation of the traction in full EHL. In this paper, a successful method for numerical calculation of the traction in partial EHL was proposed. The points of this method are very simple, and express the partial EHL traction coefficient by two factors of asperity interactions and full EHL actions. We used this method for numerical calculation and obtained satisfactory results, and could explain the effect which the surface roughness and difference between line and point contact condition exerted.
