- W3129285951 abstract "This paper considers a dynamic model of the process of mechanical bulk products’ separation in the form of a mechanical system on an elastic base. This model allows sorting grains, cereals, and other bulk products when sifting through grates and sieves and distributing them by size class. As an object of study of sorting equipment used in the processing of agricultural raw materials, we considered a vibrating screen machine. To conduct the analytical study of the processes arising from the screen movement, we proposed a dynamic model consisting of a screening surface located on an elastic base at some angle relative to the horizontal plane, of screened mass, and of vibration exciter. The bulk product is fed from above and moves through the screens, passing through several gratings or grids with different cell diameters. As the parameters determining the displacements of the mechanical system under study, we considered the ones adopted when modeling vibrations of the sprung rolling stock: bouncing, lateral bearing, twitching, pitching (galloping), and wagging. Differential equations of motion of the presented mechanical system with elastic bonds are obtained under the condition that the center of mass of the screen is displaced relative to the geometric center of symmetry on the screening surface. For this, we used the center of mass motion theorem and the one on the change of the kinetic momentum in a mechanical system of theoretical mechanics. The proposed system of differential equations of motion of a mechanical system makes it possible to numerically solve the problem, to determine its individual parameters, and to stable equipment positions." @default.
