Modeling of the Running System Pressure on the Soil Depending on the Structural Parameters of the Tractors

Abstract

The article defines the influence of the traction resistance of the machine-tractor unit working tool on the weight distribution of the tractor along the running system axles. Depending on the type of field work, the resistance force of tools aggregated with a tractor has a different value, accordingly, the tractor has a different weight distribution along the axles and, thus, different ground pressure. An increase in pressure on the soil leads to additional costs for tillage, and in the future to a decrease in agricultural production efficiency. The article presents a mathematical model for determining the reactions of the soil, and, accordingly, the pressure of tractor engines on the ground, depending on the structural parameters of the tractor, its adequacy estimation, and an example of calculating the weight distribution along the tractor axles.

Improving the quality of processing the soil environment by determining the rational structural and technological parameters for the rolling working bodies

“…The question of the mechanization of the soil tillage process, which ensures optimal soil density, and the formulation of the definition of this parameter are presented in works [14,16]. It is compliance with the value of the optimal soil density that ensures the maximum possible yield indicators of plant crops.…”

“…In addition, an increase in soil moisture content led to an increase in the degree of soil compaction, and this phenomenon was intensified in clayey soils such as loam. The influence of the pressure of the running system on the soil, depending on the design parameters of the tractors, was also deeply studied in [16].…”

“…Analyzing works [10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25], we can conclude that all research results have narrow limits of their application and are valid only for those types of soils that were studied. The existing type of rollers and the recommended modes of operation do not always correspond to the tasks that are set before them.…”

The Electric Traction Motors Balancing for Load Transfer Effects Compensation

“…The dependence of the force of draft force on the square of the working speed is found in most of the literature (Cardei et al, 2019). The modelling of the running system pressure on the soil depending on the structural parameters of the tractors according to Golub et al, (2023) is important for the characterisation of the traction system of the vehicle, especially during the normal operation of agricultural vehicles while sliding on the soil. When assessing the adherence of the tractive wheels to the ground (soil, road, rail), the adherence coefficient is a very important figure, which characterises the maximum possible torque which can be applied to the tractive axle.…”
