Abstract: Transient EHL analysis for line contacts with measured surface roughness is performed by using the multigrid method. Results show that the transient effect, induced by surface roughness, has a ...

Abstract: A fast calculation model for the pressure distribution in EHL line contacts between rough surfaces is presented. Comparison between the results obtained from the model calculation and numerical ...

Abstract: A numerical simulation of the temperature rise for a three-dimensional rough surface sliding against a smooth surface in mixed lubricated contact has been developed. The effects of lubricant ...

Abstract: The fatigue test of a needle roller bearing suggests that the dominant failure mechanism is subsurface crack initiation and propagation. Therefore, a new semi-analytical contact fatigue model is ...

Abstract: A transient model for micro-elastohydrodynamic lubrication with three-dimensional asperities in line contacts is presented in this paper. To take into account the effect of non-Newtonian behavior ...

Abstract: This paper presents a mathematical model for piston skirts in mixed lubrication. It takes into account the effects of surface waviness, roughness, piston skirt surface profile, bulk elastic ...

Abstract: This paper describes a model to study the contact between two purely longitudinally rough surfaces based on the parabolic indentor problem in elasticity. Rough surfaces are characterized with ...

Abstract: This paper deals with the distribution of asperity temperatures in the nominal contact area for purely longitudinal rough surfaces. It was found that the size of the largest asperity is ...
