• 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.
