SLIDING OF CYLINDRICAL BODIES PERPENDICULAR TO THEIR AXIS

Abstract

This paper theoretically investigates the contact interaction during the perpendicular sliding of cylindrical bodies around their own axis. For the case where the cylinder and the sliding half-plane possess identical elastic properties, the contact zone width and the normal pressure distribution laws are analyzed based on the Hertzian contact theory. The Amontons-Coulomb friction law is applied to determine the shear stresses on the sliding surface, and the influence of the positive velocity direction on the stress distribution profile is studied. The mathematical models and graphical distributions obtained from this study are of practical importance for evaluating the wear resistance of mechanical components, roller bearings, and wheel-rail contact systems.
