Modelling in FEM the soil pressures distribution caused by a tyre on a Rhodic Ferralsol soil

Non-pneumatic tire with curved isolated spokes for agricultural machinery in agricultural fields: Empirical and numerical study

“…Moreover, the low inflation pressure of pneumatic tyres provides a more uniform stress distribution on the soil surface [ 16 ] and reduces soil compaction [ [17] , [18] , [19] ]. Unfortunately, driving a vehicle with a low-inflation pressure tire may damage the tire, resulting in harm to the operator and generating waste [ 20 ]. A reduction in the inflation pressure results in a larger tire footprint, which creates more friction and heat.…”

Modeling the effect of wheeled tractors and skidded timber bunches on forest soil compaction

“…Numerous experimental studies present wheel and track designs for minimization of pressure on the soil [7][8][9]. A number of mathematical models of soil pressure distribution caused by tire have been proposed, which are based on the finite element model of soil compaction [10], smoothed-particle hydrodynamics [11], etc. Another important aspect in studying the environmental impacts of forest machinery on the soil is the interaction of skidding system with permafrost soils of cryolithic zone forests, which represent particularly susceptible forest ecosystems [12,13], and, according to [14], significantly subjected to commercial exploitation.…”

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

“…The use of analytical models requires a significant amount of experimental data on determining the parameters of the agrotechnological environment. There are a certain number of finite element models (FEM) (González Cueto et al, 2016;Silva et al, 2018) that take into account the contact interaction of running systems and allows determining soil deformations. However, most finite element models focus on determining the effect of soil environment properties on the stress distribution and deformation of the soil.…”
