Modeling and Simulation of Tire Geometry Placed on Cylindrical Surfaces

This paper studies the change of tire geometry placed on cylindrical surfaces (drums) with different diameters. The change of intended geometry includes contact patch of tire and drum and vertical displacement of tire center. Furthermore, the result of simulation of placing tire on a flat surface is compared with an actual test. The relationship between area of contact patch and diameter of drum and exerted load on tire has been obtained. Finally, the appropriate diameter of drum for road simulating test stand has been proposed.
