Abstract: This paper presents an investigation of V-ribbed belt (Micro-V™) wet friction and friction-induced slip noise in Accessory Belt Drive Systems (ABDS). A set of experiments was conducted by using an industry standard test rig and a standard material friction tester. A theoretical analysis and model are presented to elaborate the results. The tribological property of the interface is characterised to be unsteady mixed lubrication with water, which possesses the feature of negative slope of friction with velocity. The friction-induced dynamic instability and noises are also investigated. It is shown that the noise is directly associated with the negative slope of the friction-velocity curve.
