Parametrierung eines Integrierten Superelastikreifenmodells und Anwendung in der Gesamtfahrzeugsimulation

Abstract

The driving and tipping stability as well as the vibration load on the driver are considerably influenced by the tyre properties of industrial trucks. Multibody simulations are used for the detailed assessment of dynamic vehicle behaviour, which can provide precise information on vehicle behaviour. In order to be able to realistically reproduce the tyre properties within the framework of these simulations, a reliable and valid tyre model is required which introduces the occurring forces and moments into the vehicle structure. It is of particular interest that the special nonlinear properties of industrial truck tires with regard to vertical and lateral dynamics can be mapped by the model. This paper presents a three-dimensional, nonlinear tire model for superelastic tires that can be used to investigate the driving dynamics of industrial trucks during different driving maneuvers. After a short description of the basic model structure, the parameterization of the model is discussed, whereby the theoretical approach is adapted to the real tire behavior. In addition to experimental data, simulation results are used, which are generated by an own developed structural mechanical approach. The tire model is then validated or verified by comparing the simulation and measurement results, which checks its validity in various areas of application.
