<div class="htmlview paragraph">The present state of knowledge on the handling behavior of articulated combination trucks is based on parametric studies made through truck model simulations. A detailed yaw-lurch planar mathematical model for articulated log-hauling combination doglogger trucks is developed in this study. Further, a thorough kinematic and dynamic analyses of log-hauling combination trucks, incorporating a sliding drawbar is carried out and the governing equations for the lateral and yaw planar motions are derived. Using a computer simulation model, the directional performance and the yaw and lateral stability of these articulated vehicles are fully investigated through a transient and harmonic response analyses. Finally, a parameter sensitivity analysis was carried out for different variables involved in the simulation model, to study the sensitivity of the steady-state response to various parameters.</div>
