Lateral Dynamic Behaviour of Truck-Trailer Combinations due to the Influence of the Load*

Calculations using a 3-D simulation model which was verified by means of measurements from systematic field tests are used to investigate the influence of the load on the lateral dynamic behaviour of two different truck-trailer combinations by changing the mass and the yaw moment of inertia.

Critical oscillation frequencies, the lateral dynamic damping behaviour of the truck-trailer combinations and their instabilities under extreme driving conditions are discussed.
