- Abstract
For building the mathematical model of force and stress on the interference fit surface of composite back-up roll by the shrinkage fit method, the roll sleeve and roll mandrel was studied respectively. The loads acted on the contact zone was discretized and the roll sleeve and roll mandrel were discretized segment by segment, then the flexural stress and deflection models of the roll sleeve and roll mandrel was proposed based on the deformation compatibility condition. According to the force equilibrium function, torque equilibrium function between the roll sleeve and the roll mandrel, the mathematical models of forces and stress acted on the roll sleeve and interference fit surface were derived to solve the shear force, axial stress, bending moment acted on the roll sleeve and the bending moment, circumferential friction force, vertical stress acted on the interference fit surface. Therefore, it is an important theoretical foundation to improve the manufacturing technology and practical application of the composite back-up roll.
