Analytical investigations of vibratory transportation of pool materials on a horizontally stepped surface

Abstract

The work is devoted to the study of the process of vibratory transportation of bulk cargo on a special surface oscillating in a horizontal plane. The stepped surface allows the authors of the work to use vibrations in the horizontal plane, which is already an energy-saving type of transportation, since it is known that much less power is required to create horizontal vibrations than for inclined or vertical vibrations. This work explores the transportation process comprehensively: the geometric parameters of the steps and the desired parameters of the particles of the transported bulk cargo are determined and justified, all stages of the movement of the simulated cargo are established, all phase angles are mathematically determined. The possible directions of movement of the simulated load are established, depending on the kinematic parameters of vibration displacement, set by the working body. The dependence for the average speed of the movement of the cargo is obtained, the dependence of the speed of the movement of the cargo on its coefficient of friction on the working surface is also determined.
