Comparison of different tyre models for tyre/road noise applications

International audienceIn terms of safety and environment, the reduction of noise generated by tire vibrations on roads has a significant importance. In order to study the vibration properties of a tire, various models have been presented in the literature. The main purpose of the current study is a brief review of the characteristics of some models. It is supposed that the tire is subjected to an excitation caused by the contact between the tire and the road. Subsequently, the dynamic behaviour of these models are studied and compared with each other. The effects of inflation pressure and the tread patterns on the dynamic behaviour of the mentioned models are examined. For verification, the dynamical behaviour of the tire is studied experimentally. Application of the present study can be contemplated in the prediction of rolling noise and rolling resistance
