Abstract
Performance of work operations by a motor-grader is accompanied by action of asymmetrically applied external loading. As dissipative forces act between the wheels and the support surface, this force action leads to the grader deviation from the set trajectory of movement. The experimentally developed model of the vehicle behavior at performing work operations allows estimating indexes of road- holding ability depending on soil characteristics, geometric and kinematic parameters of the machine.
