Abstract

The rolling friction of a sphere over a rigid plane is studied by finite element method, where the material behaviour of the sphere is assumed to be viscoelastic, described by the Kelvin-Voigt model. The effects of contact load, radius and rotation speed of the sphere, as well as material properties such as Young s modulus, Poisson s ratio and viscosity coefficients, on rolling friction are analysed. The results support a theoretical model formulated based on the principles of contact mechanics.
