INVESTIGATING THE MOTION OF SOIL PARTICLES ON SOIL BLADES OF WORKING BODIES OF DYNAMIC ACTION

Abstract

The study of the motion of soil particles by soil blades of working bodies of dynamic action was carried out. The analysis of existing researches and publications, in which the main problem is highlighted, namely that the methodology of selecting blades, the analysis of the motion of soil particles on them at this time is not enough. As a result of the analysis of existing researches and publications, the purpose of research is set, namely: analytical researches, the result of which will allow to develop working bodies with predetermined parameters of blades and necessary modes of work, minimizing the path of passing particles of soil on them. The methodology of research is the analytical studies of the motion of particles of soil on the ground shovels. In studying the motion of soil particles on soil blades formed equations of motion of the particle of soil, and the speed of the soil fraction is obtained from the soil blade. The result of the research is a mathematical model of the motion of a soil particle on a soil-like blade, a scheme of forces acting on a soil particle has been developed, the force required for the emission of soil particles from soil blades has been obtained. As a result of the study of the motion of the soil particles by the soil-like blades of the working bodies of thedynamic action, the equations of the motion of the soil particle were obtained as a result of the transformations. An ellipsoid of rotation and an equation of force necessary for throwing the soil out of the soil elements were obtained. the practical value lies in the fact that the obtained equations allow designing the working bodies by ground treatment and the parameters of the blades that minimize the path of the passage of soil particles onto them. The originality lies in the fact that the resulting equations will allow the design of new working bodies of dynamic action with soil blades.
