Effect of Multi-Axle Steering on Off-Tracking and Dynamic Lateral Response of Articulated Tractor-Trailer Combinations

Linear yaw plane models are used to study multi-axle steering systems with a tractor and up to three full trailers to investigate how off-tracking phenomena are affected by additional steering on lateral responses during lane-change maneuvers and 90-degree turns. Linear stability analysis is used to study the dependence of critical speed(s) for lateral stability of the steered trailer axle(s)' location(s). Stability is reduced by non-steered trailer(s) addition. Drastic reduction of yaw and slip velocities, lateral forces, and high- and low-speed off-tracking, as well as the concomitant directional stability increase, results, however, from trailer steering.
