Experimental and DEM analyses on wheel-soil interaction
Journal of Terramechanics, 2018 In this paper, the wheel-soil interaction for a future lunar exploration mission is investigated by physical model tests and numerical simulations. Firstly, a series of physical model tests was conducted using the TJ-1 lunar soil simulant with various driving conditions, wheel configurations and ground void ratios.

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.

A novel soil stress estimation method of wheel-soil interaction using photoelasticity
Journal of TerramechanicsThis paper proposes a new approach to understanding the wheel-soil interaction, which is an indirect estimation method of soil stress distributions beneath a traveling wheel soil using a photoelastic method. Thus far, several photoelastic methods have been discussed for the wheel-soil terramechanics, but it is difficult for the previous configuration ...

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 ...
