Abstract

The surface roughness has a considerable impact on the success of the lubrication conditions on some occasions. The model of point contact and mathematical model of surface transverse waviness are described on the basis of the study on the characteristics of point contact with regard to surface roughness. And time-dependent solutions are obtained employing a numerical method. The elastohydrodynamic lubrication behaviors of surface transverse waviness are analyzed in pure rolling conditions

and the characteristics of film pressure and film depth varying with parameters in contact area are revealed.
