Determining the magnitude of traction force on the axes of drive wheels of self-propelled machines

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

“…To ensure the implementation of tractor traction power, it is necessary to provide a certain coupling weight in the contact area of running systems with the ground (Golub et al, 2017). An increase in the resistance of aggregates and tools that are aggregated with the tractor leads to a decrease in pressure on the ground of the front wheels and an increase in pressure on the ground of the rear wheels, which is especially noticeable when working with mounted working machines (Bauer et al, 2022).…”

“…At the same time, the authors took into account the placement of vectors of tractor traction forces at wheels point of contact with the ground. Since the ground load distribution model is based on the sum of the moments of forces relative to the wheel point of contact with the ground, this arrangement of the traction force vectors excludes their influence on the ground and, in addition, the force applied at the wheel point of contact with the ground cannot be the driving force (Golub et al, 2017). Wang and Zoerb, (1989), considers the change in axle load during tractor movement.…”

Experimental Studies of the Interaction of Tractor Drive Wheels With the Soil in the Plowed Field

“…However, the practical application of such studies is limited by the fact that when the wheel interacts with the ground, all factors act in a complex way, affect each other and have certain relationships. In (Taghavifar, H. et al, 2015;Golub et al, 2017), the factors of contact interaction are combined on the basis of the effect on the traction power of the power tool. However, studies (Taghavifar, H. et al, 2015;Golub et al, 2017) do not fully take into account the parameters of the soil environment and their changes under the influence of loads.…”

Graph-analytical optimization of the transverse vertical cross-section of a contact zone between soil and an elastic wheeled mover

“…It is possible to resolve this task on the condition of solving the problem related to reducing the levels of compacting action on agricultural soils by wheeled agricultural machinery to the agrotechnological permissible values [4][5][6]. To this end, in addition to applying results from experimental research and to employing practical experience of using mobile wheeled agricultural machinery, it is necessary to devise the scientifically grounded methods to analytically study the interaction between wheeled movers and soil.…”
