Haponenko O. Justification of the parameters of the elastic leg for disk harrow

The thesis shows theoretical generalization and new solution of scientific tasks found in the mathematical modeling of the interaction of elastic arm spherical disk with soil environment, taking into account the random nature of the reaction of the soil in the form of nonlinear dynamic model of movement. It is possible to determine the optimum dynamic characteristics of elastic arm for disk working organ, stiffness, consolidated mass, the frequency and amplitude of oscillation. The program and methods of experimental laboratory and field studies and process parameters elastic arm interaction of spherical disk with soil environment for the use of ballast paging on working body and changing forward speed unit. Evaluation results of measurements performed on the basis of the concept of uncertainty. Ballast paging influence of random components on the interaction of spherical disk on the elastic arm with the ground at least a half times less. The results of experimental studies determined depending characterizing the impact speed unit and consolidated mass on working body resistance to traction (energy index) and elastic deflection arm (agrotechnical figure). Carried out technical and economic evaluation of the efficiency of the storage unit soil structure and operating costs through implementation.
