【 摘 要 】

This work studies the dynamics of a set of rigid spherical particles in an oscillating viscous liquid under translational vibrations. Experimental data on the influence of vibration parameters and fluid properties on the formation and characteristics of structures are obtained. In the frequency range from 5 Hz to 27 Hz, particles align to form linear structures oriented perpendicular to the direction of the vibrations. For frequencies greater than 27 Hz, the particles are collected on the walls of the cavity. Distance between the linear chains increases with the vibration amplitude according to a close-to-linear law, but decreases inversely as a function of the vibration frequency.
