International Journal of Vehicle Design (IJVD), Vol. 66, No. 1, 2014

Abstract: The goal of this study is to develop a tyre model able to capture the vertical tyre dynamic behaviour while traversing over an uneven rigid surface. The proposed tyre model takes advantage of modelling the wheel-tyre assembly as a multi body dynamic system in order to investigate the tyre ride behaviour over such terrain. Several experiments are conducted for the tyre model parameter identification and the tyre model validation with an indoor quarter car tyre test rig and an outdoor portable tyre trailer test rig. The selected scenarios are simulated by using the discrete mass tyre model with the tyre parameters obtained from the experiments. The simulation results of the selected scenarios are presented and compared with the experimental data.
