Abstract
The effect of the solid body temperature effect on film thickness and traction in elastohydrodynamic lubrication (EHL) has been studied numerically. At a moderate entrainment velocity, the EHL film behavior is controlled by the solid body temperature as the oil heats up to the body temperature before entering the contact zone and thus the film thickness decreases. For high velocity conditions, inlet shear and compressive heating also contribute to the reduction of film thickness. The results indicate that the measured film thickness and traction on disc machines might be lower than the expected values when the disc temperature exceeds the supplied oil temperature.
