AB In industrial truck's driving and tipping stability as well as the vibration load on the driver are considerably influenced by the tyre properties. For the detailed assessment of dynamic vehicle behaviour, multibody simulations are used which can provide precise information on vehicle behaviour. In order to realistically reproduce the tyre properties during these simulations, a reliable and valid tyre model is required which transmits the occurring forces and moments into the vehicle structure. It is of particular interest that the model is able to map the special non-linear properties of industrial truck tyres with regard to vertical and lateral dynamics.This paper presents a three-dimensional, nonlinear tyre model for superelastic tyres that can be used to examine the driving dynamics of industrial trucks during different driving manoeuvres. After a short description of the basic model structure, the parametrization of the model is discussed, adapting the theoretical approach to the real tire behavior. In addition to experimental data, simulation results are also used for this, which are generated by means of a selfdeveloped structural mechanics approach. The tyre model is then verified by comparing the simulation and measurement results and its validity in various areas of application is examined.
