Numerical Prediction of Three-Dimensional Tire-Pavement Contact Stresses

The objective of this study is to develop a numerical modeling to simulate tires and investigate the effects of different tire and vehicle conditions on tire-pavement interactions. A three-dimensional (3-D) finite element (FE) representation of a dual-tire assembly is constructed to predict tire-pavement contact stress distributions. The tire is considered as a composite structure, including rubber and reinforcements. The tire material properties are calibrated based on the experimental measurement and data provided by tire manufacturer. The tire rolling process at different states is simulated using the arbitrary Lagrangian-Eulerian (ALE) formulation. Slide-velocity-dependent friction coefficient is used in the modeling. The constructed tire FE representation is calibrated and validated with experimental measurements of contact area, deflection, and maximum vertical contact stress. The developed FE tire-pavement interaction model is used to evaluate the contact area and mechanism of contact stress distributions at the tire-pavement interface under various tire and vehicle conditions. The distribution of contact stresses at the tire-pavement interface under different vehicle loading and speed, tire inflation pressure, vehicle maneuvering (braking, acceleration, and steady state), and rolling conditions are studied. The results clearly demonstrate the existence of non-uniform vertical contact stresses and localized tangential contact stresses at the tire-pavement interface. Investigations of the effects of applied load and tire inflation pressure show that the non-uniformity of vertical contact stresses decreases as the load increases, but increases as the inflation pressure increases. Vehicle speed does not significantly affect the vertical contact stresses. However, vehicle-maneuvering behavior significantly affects tire-pavement contact stress distributions. Tire braking/acceleration induces significant longitudinal contact stresses, while tire cornering causes the peak contact stresses to shift towards one side of the contact patch.
