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.

1. Introduction
V-ribbed belt-drive systems have become increasingly important to the automotive industry since their introduction in the late
1970s. Usually, V-ribbed belts in automotive engines drive multiple-accessory pulleys, leading to compactness, smaller pulley
diameters and a longer belt life. To ensure stable working conditions the dynamic responses of such systems have been studied
extensively. A review of the literature [1] identifies two well-defined groups of studies. The first group deals with the transverse
belt span response [2,3] and the rotational response [4] of the pulleys in the belt-drive. The second group dealswith describing the
belt-pulley contact formulation. Most of the contact models are based on classical creep theory [5] or the shear theory [6].
However, the two groups suffer an unsatisfactory connection with each other: the first does not take into account the belt-pulley
contact behavior and the second neglects the vibration due to the transmission.
Leamy and Wasfy [7,8] attemped to bridge this gap between the above-mentioned groups of studies, developing a general,
dynamic finite-elementmodel of a belt-drive system, including a detailed frictional contact. This finite-elementmodel was able to
predict the belt creep over the pulleys and the belt-drive vibrations. The contact between the belt and the pulley was modeled
using a well-known penalty method, together with a Coulomb-like tri-linear creep-rate-dependent friction law. Using the
absolute nodal coordinate formulation (ANCF), originally proposed by Shabana [9], the authors in [10] developed a more general
planarmodel of the belt-drive.Most recently, Čepon and Boltežar [11] presented a belt-drivemodel using the ANCFwith a detailed
contact formulation between the belt and the pulley. The belt-pulley contact was formulated as a linear complementarity problem
(LCP), using the discontinuous Coulomb friction law to model the frictional forces.
All the above-mentioned studies [7,8,10,11] describe belt-drive numerical models; however, no work regarding the
identification of the belt material and the contact parameters has been presented. For any reliable simulation of a belt-drive the
material and the contact parameters should be obtained from experiments. In Ref. [12], Čepon, Manin and Boltežar presented3548
