The behavior of a cylindrical body in a horizontal annulus with a longitudinal partition filled with a viscous fluid and subject to high-frequency rotational oscillations is experimentally investigated. The experiments are performed with light and heavy bodies, the density of which is only slightly different from the density of the liquid. The frequency and the amplitude of vibration vary in the experiments. With an increase in the vibration intensity, the repulsion from the boundary and suspension of the light body near the upper boundary of the layer (the heavy one—near the bottom) is found. The repulsion force acts on a solid near the boundary independently from its density. It is shown that vibrational suspension of the body in the gravity field is not associated with inertial oscillations of the body relative to the fluid but is determined by shear oscillations of the liquid itself and viscous interaction of the solid with the cavity boundary.
