Abstract

Vibrations in vehicle brake systems have been subject to research for a long time. One simple phenomenological model ist the classical friction oscillator, consisting of a mass on a belt. A closer look to a real brake system reveals that from the tyre's contact on the street to the disc the brake torque is transmitted via the tyre, which also possesses elastic, dissipative and inertial properties. Motivated by this fact an extended 2-DOF friction oscillator model is developed featuring the rim's inertia and the dissipative and elastic behaviour of the tyre. In this article the model is given and simulation results are presented. It is found, that additional torsional elasticity und damping can induce very low frequent vibrations. In addition an outlook on further studies is given. (© 2004 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim)
