Modeling of friction forces in an asymmetric two-roll module

Abstract

The study is devoted to the analysis of the patterns of friction force distribution in two-roll modules. An asymmetric two-roll module is considered, in which the rolls are located relative to the vertical with a tilt to the right, have unequal diameters and elastic coatings from the materials of different stiffness and friction coefficients, the material layer is fed with a tilt downward relative to the center line. Friction stress models and formulas for calculating neutral angles in a two-roll module under consideration are determined. Dependencies between the forces acting on the rolls and the stresses distributed under these forces are established. It was revealed that these dependences do not change with a change in the angle of supply of the material layer to the line of centers and the angle of inclination of the upper roll relative to the vertical.
