Normal and shear stress profiles along the wheel-soil contact patch for straight-driving wheel
This talk will present simulations for vehicle mobility in deformable soils using Discrete Element Method (DEM) performed at the Center for Advanced Vehicular Systems, Mississippi State University. Results of the DEM simulations using coarse-scale DEM soil models to predict tractive performance of a wheel in deformable soils will be shown and compared with published experimental data and empirical relationships.
Final configurations of the wheel in particle bed at 54.8% slip (upper row) and -5.9% slip (lower row) with 3° (odd columns) and 12° (even columns) side slip in two different materials
