The Tire Model in the Simulation of The Tractor Motions

The influence of tire characteristics is investigated by the simulation of an agricultural tractor. First the simulation of the tire is discussed. Different models are proposed and evaluated on their validity and their applicability . Also the practical measurement of some parameters is discussed. In a second paragraph the tractor model used in presented. In a second paragraph the tractor model used is presented. In the third part some results of the simulation are communicated . Beside the normal motions along and around the lateral axis, special attention is attracted on the hop. But one of the conclusions is that the simulation of hop is not possible without non-linear elements.
