Modeling Heavy Wheel Loading on Frozen and Unfrozen Ground
Two ABAQUS 3-D Finite Element Models (FEM) were constructed with hyper-elastic rubber tires loaded on unfrozen and frozen ground conditions (0, 7.62, 15.24, 22.86, and 30.48 cm frost depths), one contained a statically loaded tire, and the other contained a tire rolling at 8.05 km/h. The ground was constructed of multiple layers, allowing each of the respective frost depths to be adequately modeled. This was accomplished by changing the material properties in the layers to match the given frost condition. The material models used in the FEM simulations are representative of a frost-susceptible soil, which was used in full scale unpaved road tests at CRREL. The interest in this modeling is to see how the stress and displacement change as a function of frost depth as a heavy tire rolls over the surface. Stress and displacement data collected from the ABAQUS FEM simulations are compared to experimental data. The results show similar trends between the ABAQUS and experimental data for vertical displacement and vertical stress below the contact patch.
