Аннотація: 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 th e 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.
