Rut depth generated in dry sand at 10 kmph (left) and 20 kmph (right) longitudinal speeds.
This session will introduce the concept of virtual soil moisturization and its impact on the performance of 315/80R22.5-sized truck tires. The truck tires are simulated using multiple layers and materials in a Finite Element Analysis (FEA) environment. Moist sand, composed of layered water and sand particles, is simulated using the Smoothed-Particle Hydrodynamics (SPH) technique. The numerical interaction between sand and water is determined using Darcy’s law. The tire-sand interaction is defined by a hybrid FEA-SPH interaction model, and the tire's tractive performance—including tractive effort, motion resistance coefficient, and tire sinkage—will be presented. Finally, the challenges of validating such models will be discussed, along with future work on developing more advanced tire-terrain models.
