“…Moreover, for the bias-ply tires, there were small changes in the width and length of the footprint as a result of changing the inflation pressure, which only further confirms the hypothesis that the inflation pressure has a large impact on increasing the stiffness of the tire and, consequently, on its deeper impact. Slightly different relationships were demonstrated in work [27], where a bias-ply tire was inflated to three pressures (0.10, 0.16, and 0.32 MPa), and with the increase in pressure, a decrease in the actual footprint area was observed each time. In this case, the maximum difference in values of the actual footprint area at extreme inflation pressures (0.100 MPa vs. 0.325 MPa) was 86%, while in the current results, this difference does not exceed 44%.…”

“…While there are no major technical problems when measuring tire deformations, they may arise when trying to record what is happening under the soil surface as a result of compaction [15]. There are many studies that attempted to determine stresses in soil and their distribution [27][28][29][30][31][32]. Due to the mentioned technical difficulties related to measuring stresses inside the soil, innovative simulation techniques such as the Finite Elements Method (FEM) are increasingly used-this method was used in the works [33][34][35].…”

This paper presents an innovative method to determine the impact of agricultural wheels on soil. The experiment was conducted under controlled conditions, and the parameters of the tire footprints on the soil were analyzed. The tested parameters were the width, length, and depth of the footprint, the cross-section area of the tire, and the area of the footprint. All parameters were determined using the 3D scanning method. Two types of tires, two levels of vertical load, and three levels of inflation pressure were used. The aim of the research was to demonstrate differences in changes in the footprint parameters as a result of changes in the operational parameters of the tires. It was found the bias-ply tire was less responsive to changes in the width and length of the footprint than the radial tire. Moreover, it was shown that radial and bias-ply tires achieved similar values for the footprint area but in the case of bias-ply tires, there was a much greater footprint depth. This means that the side parts of the footprint of bias-ply tires have a more vertical profile, so they carry the vertical loads to a lesser extent.

“…The geometric nonlinearity of the processes of soil deformation under the movers of mobile machinery predetermines the need for a graph-analytical study of the deformation dynamics not only of the deformed environment (soil) but the elastic [2,9,14] deformer (mover). In this case, the dynamics of a contour of contact surfaces of soil and the elastic mover sheath can be considered to be a certain generalization of the geometric characteristics of shape change in the soil microrelief under the mover of a mobile technological vehicle.…”

“…This leads to the intensification of anthropogenic impact on the fertile layers of soil, which reduces their ferti lity: their natural structural organization is overcompacted, water-air soil regime is disrupted, the physical, chemical, technological properties deteriorate, etc. [1][2][3]. The above renders special significance to one of the most urgent problems in modern agrarian production, which relates to improving the technological indicators in the operation of running systems of wheeled mobile agricultural machinery.…”

Інтенсифікація сільськогосподарського виробництва в сучасних умовах передбачає застосування надпотужних мобільних технічних засобів, що призводить до підвищення рівнів техногенного впливу на ґрунт і, як наслідок, погіршення його родючості. Тому, найактуальніший запит сучасного аграрного виробництва спрямований на вирішення проблеми покращення експлуатаційних показників роботи колісних ходових систем мобільних технічних засобів. Це спонукає до необхідності аналітичного дослідження процесів деформування ґрунту під еластичними рушіями мобільної колісної техніки сільськогосподарського призначення. Запропонована методика графо-аналітичного поетапного моделювання процесу деформування ґрунту під пневматичними шинами рушіїв мобільної сільськогосподарської техніки з урахуванням змінюваної форми еластичної оболонки шини. Використання відповідних графічних моделей дозволяє поетапно досліджувати процес ущільнення ґрунту у профілі утворюваної ним колії. Встановлено, що в зоні контакту «деформований ґрунт-поверхня еластичного колісного рушія мобільного засобу» найвищий рівень ущільнення спостерігається в шарі ґрунту, який безпосередньо контактує з еластичним рушієм. Глибина переущільненого шару ґрунту на «дні колії» залежить від типорозміру шини колісного рушія і не перевищує значення 0,075 ширини шини. Найвищий рівень переущільнення ґрунту спостерігається в зоні, яка є безпосередньо прилеглою до осі колії. Визначено, що найнебезпечнішою конструкцією пневматичної шини, з точки зору переущільнення ґрунту в колії, є форма еластичної оболонки шини, яка описується кривою овалу Кассіні з чотирма точками перегину. Окреслено характерні особливості рекомендацій щодо визначення експлуатаційних значень робочого тиску у шинах залежно від конкретних фізико-механічних та агротехнологічних властивостей ґрунту і характеру виконуваних технологічних операцій Ключові слова: ущільнення ґрунту, еластичний деформатор, поле сил тиску, нелінійність деформування ґрунту

“…More advanced forms of research use computer techniques-such as the finite element method-to determine soil deformation. For example, González Cueto et al [16], González Cueto et al [17], Khot et al [18], Nakashima and Kobayashi [19], and Smith et al [20] used the finite element method to analyze tire-soil interaction. In contrast, the work of Nakashima and Oida [21] and Michael et al [22] used a combination of the finite element method and the discrete element method to represent the model in the tire-soil system.…”

This research presents the results of tests conducted under field conditions and included measuring the footprint of tires on soil. Two agricultural tires of the same size but different internal structures were tested, 500/50R17 (radial) and 500/50-17 (bias-ply). The factors were tire inflation pressure (0.8 bar, 1.6 bar, and 2.4 bar) and tire vertical load (7.8 kN, 11.8 kN, and 15.7 kN). The footprint made on the soil was scanned with a 3D scanner, resulting in a digital image of the tire footprint on the soil to enable an analysis of the measured parameters: length, width, depth, and contact area (in 3D form). Statistical analysis showed that for radial tire footprints, both inflation pressure and vertical load had a significant effect on all analyzed parameters. For bias-ply tire footprints, it was shown that only inflation pressure had a significant effect on all of the analyzed parameters, while the significance of the effect of the vertical load was not confirmed for the footprint depth. Based on the results obtained, the suitability of models describing the relationship between operating factors and the actual footprint area was verified. It was found that for a radial tire, the model formulated based on laboratory tests can predict the contact surface under field conditions (the correlation coefficient R2 was equal to 0.9226). In the case of a bias-ply tire, the correlation coefficient R2 reached a value equal to 0.5828. This indicates a less accurate estimation of the surface area under field conditions based on the model designed after laboratory testing.
