Optimal parameters of the tractor and arable unit for various optimization criteria

Abstract

The article is devoted to identifying the optimal values of the main parameters of the tractor (its weight and engine power) and the unit (the width of the plow capture and the working velocity of the unit) according to various optimization criteria: minimum straight and indirect total energy costs taking into account the energy of a lost harvest; Minimum emission of carbon dioxide at the stages of manufacture and operation, taking into account the amount of carbon dioxide, which could be absorbed from the atmosphere, lost during the work of the unit, crops; maximum aggregate performance in one hour of time The minimum fuel consumption per ha was treated as an area of the area and the maximum traction tractor efficiency. According to the results of computational experiments using mathematical models of the arable unit, it was revealed that the optimal values of the main parameters of the tractor and the unit coincide according to the first three optimization criteria and for the selected working conditions are: the weight of the tractor 130 kN; engine power 398 hp; the width of the capture of the unit is 5.25 m; working speed is 7.5 km / h.
