Abstract: One of the most accurate methods for simulating numerous nonlinear systems is finite element analysis (FEA). However, when it comes to modelling non-meshed particles, smoothed particle hydrodynamics (SPH) is used to obtain more reliable results. The modelled FEA truck tyre is similar to a wide base truck tyre having specifications of 445/50R22.5. The tyre is previously validated through different simulations such as contact foot print, static deflection, dynamic first mode of vibration, and various rolling resistance tests. These simulations are performed under different inflation pressures, vertical loads, and speeds. In this research, the tyre is validated on soft soil, while considering various combinations of parameters. These parameters affect soil characteristics to reach an optimum and calibrated soil model corresponding to the existing empirical data for dry sand. This research will be heading toward developing an off-road rigid ring model in future projects.
