Abstract
The motion of a body in a periodic potential relief with weak damping is considered. It is shown that, in the presence of an additional periodic external action, dependence of the period-average velocity on the mean force of friction exhibits plateaus where variations in the acting force do not lead to changes in the average velocity. The plateau velocity is proportional to the frequency of the applied periodic perturbation and can be readily controlled. The effect can be used to create the driving mechanisms capable of ensuring motion at a strictly preset velocity not affected by the applied load variations.
