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.
