Dynamical Shear and Structural Viscoelasticity in Elastohydrodynamic Lubrication.
Abstract
The thrust of this paper is to address the question of what dynamical properties of a viscoelastic liquid lubricant are instrumental in determining the traction in a heavily loaded rolling contact. In examining this question the dynamical changes that the large normal stresses in the contact zone produce in the lubricant film are explored. The effect of these structural changes on the response of the liquid to the imposed shear is then evaluated; from this, the shear stress profile in the contact-which determines the traction can be computed.
