DISPLACEMENT OF BODIES WITH TOSSINGON A VIBRATING SURFACE N. A. Dokukova and M. D. Martynenko UDC 539.0 A new approach to investigations of structural mechanisms that accomplish displacement of bodies with tossing on a vibrating surface is suggested that explains some facts that are widely known from experiments. This approach makes it possible to select criteria for optimization of the geometric parameters and physical charactersitics of the objects created that provide a reduction in mechanism loading and economy in energy resources.
