Mehrkörpersimulation in der Fahrdynamik von Ackerschleppern

Abstract

The driving speed of modern tractors increased within last years up to 60 km/h. Together with the driving speed, the safety and comfort requirements are increasing as well. Since modern agricultural tractors still don’t have a rear axle suspension, their driving dynamics behaviour can become critical at certain situations. To be able to predict such critical situations, a multibody model of a tractor can be used. This paper presents the MBS-Model of a tractor which is coupled to a transient tyre model – the Hohenheim Tyre Model. Finally, some validation results are shown. Therewith, a basis for further vehicle improvements using the presented driving dynamics model is set up.
