• Abstract:
  Accurate modeling of tire‐pavement contact behavior (i.e., distribution of contact tractions at the ; interface) plays an important role in the analysis of pavement performance and vehicle driving safety. ; The tire‐pavement contact is essentially a rolling contact problem. Many aspects, such as the transient ; contact with nonlinear frictional properties at the tire‐pavement interface, make the rolling contact ; problem more difficult than it may appear at first glance. The nonlinear frictional contact could ; introduce numerical difficulties into the finite element method (FEM) solution because the contact area ; and distribution of the contact tractions are not known beforehand. Therefore, it is appealing to ; formulate and implement high‐fidelity FE models capable of accurately simulating the tire‐pavement ; contact behavior. However, obtaining an accurate frictional relationship is difficult for tire‐pavement ; interaction. The friction between the tire and pavement is a complex phenomenon depending on many ; factors, such as viscoelastic properties of rubber, pavement texture, temperature, vehicle speed, slip ; ratio, and normal pressure. Field measurements have clearly shown that the friction between the tire ; and pavement is dependent of vehicle speed and the slip ratio at the vehicle maneuvering processes. ; In this research, a three‐dimensional (3‐D) tire‐pavement interaction model is developed using FEM to ; analyze the tire‐pavement contact stress distributions at various rolling conditions (free rolling, ; braking/accelerating, and cornering). In addition, existing friction models for tire‐pavement contact are ; reviewed and the effect of interfacial friction on the tire‐pavement contact stress distributions is ; investigated.
