Numerical simulation of tire steering on sandy soil based on discrete element method

The steering performance of off-road tires on sandy soil has a great influence the maneuverability vehicle, which long been studied by scholars. However, discrete element method (DEM) modeling tire sand is still lacking. In this paper, an model established using method, and parameters are calibrated based triaxial compression test inclined plate experiment. Then, verified reduced-scale single wheel bin under straight-driving condition. Finally, radius, roll angle, slip rate process studied. results show that reduction in radius slight drawbar pull driving torque but greater growth lateral force, aligning torque, sinkage. sideslip angle play important role pull, drive torque. small force
