Statistical Model for Calculation of Mass, Power and Traction Characteristics of Agricultural Tractors

This paper considers a new principle of designing autonomous mobile transport-technological machines of agricultural purpose through the construction of statistical model of parameters calculation. Design of the chassis should take into account the terrain of functioning and agrotechnological requirements with the possibility of adaptation to changing environmental conditions. The new approach consists in determining the initial parameters of the chassis by using analytical dependencies of the existing traditional chassis schemes of agricultural tractors on wheeled and tracked tractors on wheeled and tracked propulsion. The result of the research is obtaining of mathematical dependencies, which allow to select the optimal mass and traction-power characteristics, which will ensure the competitiveness of the autonomous mobile complex.
