This thesis deals with air-pumping mechanisms leading to tyre/road noise in the case of a slick tyre rolling on a cylindrical road cavity. A CFD model was used to calculate the dynamic air pressure variation at the cavity bottom, assuming a volume variation of this cavity during contact with the tyre. A piston method was validated in order to model this volume variation by a vertical displacement of the cavity bottom, equivalent to the volume variation caused by the tyre tread penetration during contact. The volume variation used in the piston model was determined first numerically by a contact model and then experimentally by measuring the penetration of the rubber on a test rig. The latter was also used for the measurement of dynamic air ...
