In order to overcome prediction defects of the current tire friction mechanism model on ice surface, this paper puts forward a tire–rubber–ice surface traction prediction model by integrating the Levenberg–Marquardt (LM) optimizing algorithm with the neural network. With 125 groups of experimental data of different influencing factors as training samples, the LM optimizing algorithm is adopted to...
This paper presents the lug effects of off-road wheel in terms of lugs’ height, type, intersection and central angle. To improve the tractive performance of transport vehicles and equipments operating on dry sands nearshore, this paper numerically presents the wheel–sand interaction by the discrete element method (DEM), which is better dynamically accurate than FEM in the study of incompact terrain-like...
