A three-dimensional numerical model of wheel/rail in rolling contact is established to study the adhesion characteristics under interfacial contamination considering surface roughness at high speed. The thermal partial elastohydrodynamic lubrication (EHL) theory in elliptical contact is used in the model. The numerical model is successfully solved by applying the iterative algorithm between the pressure...
A preliminary two dimensional numerical model of wheel/rail in rolling contact is established to study the adhesion characteristics of wheel/rail with considering surface roughness under oil and water mixed contamination. A partial elastohydrodynamic lubrication (EHL) theory in line contact is applied in the model. The present numerical model is used to investigate the effects of contact pressures...
