3. The Rolling Friction, and the Sliding Friction under Lubrication

Abstract

The mechanisms of rolling friction and the sliding friction under lubrication are explained. These phenomena of rolling friction were experienced in the friction of tires and ball bearings. The boundary lubrication, mixed lubrication, hydrodynamic lubrication and elastohydrodynamic lubrication were also discussed in this paper.
