This paper presents an investigation of V-ribbed belt 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 (modified SAE belt friction/slip test rig). A theoretical interpretation was presented and a simplified model was used to elaborate the unsteady friction characteristics. 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 (self-exited belt vibrations) is directly associated with the negative slope of friction with respect to velocity.
