Relation of the stress state in the contact zone and the forces acting in the roller mechanisms

Abstract

Mathematical models were developed to study the distribution pattern of shear and friction stresses in the roll contact zone. These models establish a relationship between the stress state in the contact zone, the forces acting on the roller mechanisms, and the shape of the roll contact curve in driven and free rollers. The distribution of normal stresses determines the distribution of shear stresses along the contact curve, the compliance of the material strip and the roller coating, and the forces acting on the roller mechanism.
