Simulation of contact voltages in two-roll modules

Abstract

Abstract Mathematical models of the regularities of the distribution of contact stresses in the generalized two-roll module are obtained. These models take into account all the main parameters of two-roll modules and describe the distribution diagrams of contact stresses for all special cases of interaction of the processed material with pairs of rolls in two-roll modules. 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.
