An investigation of how road roughness affects the tire-pavement interface for an articulated vehicle has been completed. A modified version of the three dimensional vehicle simulation, TDVS3, was used to simulate braking and cornering maneuvers for an articulated vehicle on different road surfaces of varying severity. The results of this investigation show that the effects of road roughness are greatest when the vehicle is performing maneuvers near its performance limit. For example, introducing road roughness to a severe cornering maneuver for which the vehicle had been stable, resulted in large enough increases in the vehicle's roll angle and lateral acceleration to cause the vehicle to become roll unstable. Likewise for a severe braking maneuver, introducing road roughness caused a twenty percent (20%) increase in the vehicle's stopping distance. These extreme effects were not manifested for less severe cornering or braking maneuvers that would typically be encountered in nominal driving situations.
