Distribution of contact voltages in asymmetric two-roll module

Abstract

Abstract Mathematical models of the regularities of the distribution of contact stresses in the generalized two-roll module in the case when the nature of the deformation of the material layer is specified by rheological models are obtained. New data on the regularities of the distribution of contact stresses are revealed: normal contact stresses change from zero at the beginning and at the end of the contact zone of the rolls to a maximum at a point lying to the left of the center line (towards the beginning of the contact of the rolls); the tangential contact stresses change their signs at the neutral point, which in the driven roll is located towards the entrance of the material layer into the contact zone of the rolls, and in the free one - towards the exit; during static interaction of the rolls with the material being processed, the point of maximum normal stresses and the neutral point are located on the center line.
