Mathematic simulation and calculation of soil compaction by the work of wheeled tractor and after its stop

Zolotarevskaya D.I., Goncharova Z.G.


The modification of the stressedly-deformed state and the density of viscoelastic sandy-loam soil as a result of the sequential passages of the wheel tractor with the different speeds on the soil were investigated. Viscoelastic properties of the soil are described with the first order differential equation connecting the compressive stress, the speed of the change of the compressing stress and relative deformation of the compression in the vertical direction. A method of calculation of the deforming indices and the compacting of the soil because of the creep after tractor has stopped was offered. In the computing experiments, the calculated data which characterize the influence of the row of factors on the viscoelastic properties of the soil and the compressing action of the tractor on the soil was obtained.

Mathematic simulation of separating potato tubers on the roll-and-disk surface

Oreshin Y.Y.


The paper presents a mathematical method for calculation of the optimal slope of the directing disk to the rotation axis of roller-and-disk sorting tool. Analysis of the obtained results shows that the choice of rational parameters and operation modes of the above tool improves the grading accuracy and lowers the tuber damage thus raising efficiency of potato grading machines.

Simulation of grain destruction process with the use of computer

Solntsev R.V.


The article aims at examining the grain destruction process. This process is widely used in manufacture of mixed fodders. Current methods are not optimal, as they take into account separate aspects of the process. Also there is no specialized software for modeling. The article presents a computer program in Delphi, which allows to model the grain destruction process and to explain the functional relations between its parameters. This program will be most useful for determination of boundary values of researched parameters.
