Experimental identification of the contact parameters between a V-ribbed belt and a pulley

The aim of this paper is to identify the contact parameters between a belt and a pulley that can be used in a two-dimensional multibody belt-drive model. Two experimental setups are proposed in order to identify the contact stiffness and the friction coefficient between the V-ribbed belt and the pulley. The friction coefficient is identified at various initial belt tensions and relative velocities between the belt and the pulley. The measurement procedure and the contact formulation are verified with a numerical experiment.
