Annotation

The article presents the results of studies of the interaction of the plowskin part of the mole farmer with soil. The purpose of the study is to determine the rates of relative deformations depending on its geometric and kinematic parameters. This will make it possible to determine the magnitude of the stress components and soil density functions that depend on these stresses. In addition, this will allow us to determine the strength of the soil resistance to the movement of the plow share of the mover.
The soil is presented in the form of a model of a viscoelastic medium in such a way that bigaromic potential functions can be used to analyze the interaction, since the final equations are reduced to a system of elliptic equations. Such a statement of the problem and its solution make it possible to obtain dependences of the relationship of the geometric parameters of the ploughshare part of the mover with the components of the strain rates of the soil, as well as the mechanical properties of the soil on the surface of its contact with the ploughshare. These expressions are the initial ones for the further determination of the components of stresses in the soil, which make it possible to determine the compaction of the soil on the walls of the formed cavity for drawing the anti-filter screen and the components of the resistance forces to the ploughshare.
Obtaining the final expressions of soil compaction on the molehill walls together with the dependences of the resistance forces will allow us to determine the geometric parameters of the working body, with various mechanical properties of the soil, to ensure the stability of the molehill walls with minimal energy consumption.
Such a solution is common for a certain class of problems on the interaction of the working body with the soil, which is represented by a deformable medium in order to determine the directions of changes in deformations or their velocities in order to use them to determine stress components that will allow you to find zones of possible plastic deformations and destruction of soil continuity.

Keywords: components of deformations or stresses, component of traction resistance, ploughshare working body, biharmonic potential function, components of displacement velocities, continuum theory, component of relative deformations, component of stresses in soil, ploughshare share.

History of journal:

In June 1994 the 2nd International Scientific and Technical Conference "Application of vibrations for technological purposes" was organized on the basis of Vinnytsia State Agricultural Institute. Leading experts in this field, noting the significant contribution to the school of Vibration Engineering under the leadership of P. S. Bernyk, proposed to create a professional all-Ukrainian scientific and technical journal "Vibration in engineering and technology..The journal was foundedat Vinnytsia State Agricultural Institute and P.S. Bernyk was elected to be the chief editor .
For all these years (since 1994) theJournal "vibration in engineering and technology" published  94 issues wherestudy of vibration effects, the creation of progressive energy saving technologies and equipment for their implementation were highlighted.
Currently Kaletnik H.M  PhD , professor, academician NAAS is the chief editor of the "Vibrations in engineering  and Technology"
The journal "Vibration in Engineering and technology", which has no analogues on the territory of Ukraine, is well known abroad.
