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

Abstract

The article defines the influence of structural and operational parameters of a machine-tractor unit on changes in the hardness of freshly plowed soil due to deformation and compaction of the soil by wheeled running systems. An experimental model of the effect of pressure in the pneumatic chamber of the wheel, working width and speed of the unit on changes in soil hardness in the area of operation of running systems is obtained. The obtained mathematical models make it possible to predict changes in soil hardness, which makes it possible to reduce the negative impact on the soil of running systems by optimally completing, configuring and selecting the MTU operating mode.

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

“…During fieldwork, tractor wheels interact with the fertile soil layer. As a result of the force interaction, the phenomena of soil deformation and compaction are observed (Golub et al, 2021;Mileusnić et al, 2022). Therefore, biological processes in the soil are disrupted (Keller et al, 2022), which leads to a decrease in field crop yields (Nawaz et al, 2012;Mueller et al, 2010).…”
