On the question of determining the kinematic parameters of combine harvesters

Abstract

The proposed article provides methodological approaches for determining the kinematic indices of new grain combine harvesters, for which information in the source data is not yet available in literary sources. This method makes it possible to conduct analytical studies on the use of modern grain combine harvesters. In the given article also the results simulation methods movement and circuits turning movements on coefficient work moves and coefficient of turning behavior. The traditionally, the kinematic indices use of machine aggregates in crop production are determined, on technical specifications grain combine harvesters in productive conditions, and the known operating parameters of grain combine harvesters choose the required methods of movement and circuits turning movements, thus efficiency of use to the optimum value, but within a certain range of technologically accepted values. The recent periods scientific research on this topic are aimed at determining the rational structure of costs for the implementation technological processes through substantiation the composition machine aggregates and their modes of operation. The rationale for rational compositions and kinematics indices of grain combine harvesters should be based on a system of mathematical models that reproduce the interdependence between the working conditions and the requirements for technological processes. The purpose of the work is to provide methodological approaches for determining the kinematics indices use of harvesting complexes, depending on the size of the fields, which will allow to further arrange the choice one of the alternative aggregates according to the necessary criteria. The increasing the size of the fields that are harvesting of new grain combine harvesters leads to an improvement of their technical and operational performance: the unit's productivity increases, while the incremental fuel consumption decreases.
