Manipulation of a part on a vibrating plane under controlled dry friction

Abstract

Motion of the part over the horizontally excited in two perpendicular directions plane, under controlled dry friction coefficient between the plane and the part, is ana-lyzed in the paper. Motion trajectories of the part during positioning and search were defined, as the plane is excited along the circular and elliptic trajectories and friction coef-ficient is controlled in one and both the semiperiods of the excitation signal. There were defined dependences of the part displacement, from the initial position towards the center of the steady state trajectory, and directional angle of the motion trajectory both on the moment of decreased friction, relative to the excitation signal, and on duration of the maintained decreased friction.
