A yaw roll model is proposed for investigating the effect of roll motion and suspension on the lateral dynamic behaviour of various design configurations of log hauling trucks. A detailed kinematic and dynamic analysis of this model for the truck tandem axle pole trailer combinations is carried out, and the corresponding equations of motion are established. The directional response and roll response under step and sinusoidal steer maneuvers are investigated numerically. The results obtained show that the suspension and roll motion have a significant effect on the final steady state motion in the lateral direction.
