The oretical justification of placing a vibration generator on a cultivator rack

It is analytically proved that in order to ensure the minimum energy costs spent on the operation of the vibration generator, it is necessary to place it at the point corresponding to the intersection of the horizontal line with the center of gravity of the cross section of the cultivator rack.

Introduction. One of the main directions of the development of the agro-industrial complex in the field of agricultural production is considered an increase in soil fertility and an increase in the efficiency of the functioning of machine and tractor units (MTU). The quality of products and high yield of cultivated crops is an important task of agricultural production. The transition to innovative designs of tillage machines, allows you to achieve all the necessary indicators: agro technological, energy and environmental. The focus is on the energy saving strategy, the basic principles of designing tillage tools are proposed, which are based on fundamental studies of the physical, mechanical and dynamic characteristics of the soil background.

Object. The object of research is the technological process of tillage with cultivator MTU.

The subject of the study is the energy and quality indicators of the technological process of tillage with a cultivator MTU with active working bodies.

The purpose of the study is to develop a conceptual framework for improving the energy-technological indicators of cultivator MTU with vibration of working sections.

Materials and methods. The methodological basis of the research was the methods of system analysis, synthesis and theoretical provisions, the laws of soil theory, resistance of materials, theoretical mechanics, theory of oscillations and mathematical statistics.

Results and conclusions. According to the criterion formulated in the work, such a location of the vibration generator was selected so that a linear dependence remained between the generated (disturbing) force and the movement of the toe of the working organ of the cultivator section, which contributes to a resonant increase in the oscillation amplitudes of the cultivator rack. Thus, in order to ensure the minimum energy costs spent on the operation of the vibration generator, it is necessary to place it at the point corresponding to the intersection of the horizontal line with the center of gravity of the cross section of the cultivator rack.
