Calculation method of modeling of deformation properties of soils in the forecasting problems of interaction of wheeled mover with the bearing surface
Abstract
The article deals with a technique of modeling of deformation properties of soil bearing surfaces using the finite elements method in nonlinear dynamic formulation for problems related to the passability assessment of wheeled vehicles. Using of the technique will allow to specify the calculation of mutual deformations of tyre and soil bearing surface, to forecast the level of passability of wheeled vehicles depending on the intended area of operation at design stage.

Evaluation of statistical characteristics of flow of grain pile entering in dryer
Abstract
Dynamics of changes in characteristics of the flow of grain pile entering in dryer have been analyzed on basis of experimental data. Stochastic mathematical model determining the initial operating conditions of dryers is constructed. The model allows to simulate the operating conditions of dryers regardless of their throughput capacity.

Substantiation of kinematic diagram of stroke drive of agricultural bridge aggregate
Abstract
The article considers the force interaction between stroke drive of bridge aggregate with frictional kinematic connection of supporting-driving wheels and the guide track. Calculated values of power factors leading to misalignment of agricultural bridge aggregate in relation to the guide track are obtained. A new kinematic diagram of drive of bridge aggregate preventing misalignment and providing plane-parallel motion on the guide track is given.

Assessment of white lupine grain damage during harvesting
Abstract
Factors affecting the quality of threshing of white lupine grain during harvesting are described. Settings of threshing and separating system of КЗС-1218 Palesse GS12 combine harvesters are analyzed. Dependence of seed damage on the rotating frequency of threshing drum and on the gap between threshing drum and concave is determined. Recommendations for adjustment of threshing and separating system of the harvester are given.
