THE RESEARCH OF INERTIAL CONVEYOR TRANSI-TIONAL CHUTE OSCILLATIONS INFLUENCE ON ITS TECHNICAL AND ECONOMIC INDICATORS

English abstract

The construction of an inertial conveyor for bulk materials transportation has been elaborated in order to increase productivity and reduce the energy intensity of the bulk materials transportation process. The inertial conveyor consists of a chute, which performs reciprocating motion on a fixed basis and actuating the reciprocating movement of the chute. The chute can perform not only a reciprocating motion, but also a movement in a direction that is perpendicular to the axis of the conveyor in a horizontal plane. It has been proposed to reduce the friction force between the load and the chute at a time when the speed of the chute relative to the load will be di-rected in the opposite direction. The analyses of known methods of solving nonlinear differential equations, which describe the motion of mechanical systems in the pres-ence of dry friction has been done. A mathematical model of a bulk material particles motion over a surface that performs a harmonic motion has been elaborated. A con-struction of efficient inertial conveyor has been created. The influence patterns of structural and kinematic parameters of the inertial conveyor on the indicators of bulk materials transportation process by this vehicle have been experimentally investigat-ed. A mathematical model of the flow of a bulk material in a rectangular chute that performs high intensity transverse oscillations in the plane of greatest inclination has been developed. It has been established experimentally that, in the presence of such oscillations, the material retains the shape of the chute and therefore its motion can be regarded as the motion of a solid on an inclined surface. The averaging method obtained an approximate solution of the equations of this motion, which satisfactorily agrees with the results of experimental studies. The obtained dependences of the average velocity of the bulk material on the sur-face of the chute from the angle of inclination to the horizon and the coefficient of friction of the material on this surface can be applied in engineering calculations for solving specific practical problems.
