Impact of vertical load, multiple passes, and speed on rut depth in soil under pneumatic and track wheels [PDF]
Scientific ReportsWhen vehicles pass over soil, ruts are created in the soil, the effect of which can be found in soil compaction. This research was conducted to investigate and rank the effect of vertical load, multiple passes, and forward speed on rut depth.

Discrete Element Modelling of Soil Compaction of a Press-Wheel
AgriEngineering, 2021 Press-wheels are wheels designed to compact the soil above seeds in the “seed cover” region. Soil compaction, produced by the press-wheels of seeders, affects seedling emergence and early plant growth.

Wheel rolling on deformable ground with slippage [PDF]
E3S Web of Conferences, 2022 Wheeled vehicles can move not only on a solid supporting surface, but also on deformable surfaces (snow, ground, sand, etc.). When a pneumatic wheel with a high internal air pressure rolls over deformable soil, the nature of the wheels’ interaction with ...

Simulation of the Wheel-Surface Interaction Dynamics for All-Terrain Vehicles
Applied Mechanics, 2022 In this paper, a new methodology for the numerical simulation of the wheel–surface interaction has been presented. The finite-element method was combined with the discrete-element method, rigid body dynamics, and the advanced wheel–surface friction model.
