Abstract: |
By using analytical correlations
derived as a result of theoretical research, a computer algorithm has been
worked out for simulating the functions of the plough body and the forces
exerted by soil upon the operating parts, as well as its draft resistance.
These correlations allow to determine the draft
resistance of the plough depending on the parameters of its body, as well as
to evaluate the impact of the physical and mechanical properties of soil,
such as friction upon it. The greatest influence upon the
draft resistance is exerted by soil hardness, density and slip resistance
along the surfaces of the operating parts. The latter is also affected
by soil adhesion, which particularly manifests itself in wet clay soils at
lower temperatures. It has been clarified that the friction resistance
constitutes 46 – 62 % of the total draft resistance of the plough body. The
main ways of lowering the friction resistance and the total draft resistance
of the plough are the introduction of a more rational design of its body
having optimum parameters, decreasing the resistance of the share-mouldboard
surface and the values of reactions of the supporting surfaces, as well as
the application of antifriction materials and better modes of joining with
tractors. |
