本文介绍了一个三维轮胎-路面相互作用模型的发展，以预测轮胎-路面接触应力分布，为今后使用的路面响应的机理分析。将带肋子午线轮胎建模为橡胶和增强体的复合结构，通过载荷-挠度曲线标定轮胎材料参数。稳态轮胎滚动过程模拟使用任意拉格朗日欧拉公式。模型结果与以前的测量结果是一致的，并验证了非均匀的垂直接触应力和局部切向接触应力的存在。分析结果表明，垂直接触应力的不均匀性随载荷的增加而减小，随充气压力的增加而增大。然而，车辆操纵行为显着影响轮胎路面接触应力分布。例如，轮胎制动/加速引起显著的纵向接触应力，而轮胎转弯导致峰值接触应力朝向接触面的一侧移动。模型结果提供了宝贵的见解，了解现实的轮胎路面相互作用，分析路面响应在临界荷载条件下。
This paper describes the development of a 3D tyre-pavement interaction model to predict the tyre-pavement contact stress distributions for future use in the mechanistic analysis of pavement responses. The ribbed radial-ply tyre was modelled as a composite structure (rubber and reinforcement), and the tyre material parameters were calibrated through load-deflection curves. The steady-state tyre rolling process was simulated using an arbitrary Lagrangian Eulerian formulation. The model results are consistent with previous measurements and validate the existence of non-uniform vertical contact stresses and localised tangential contact stresses. The analysis results show that the non-uniformity of vertical contact stresses decreases as the load increases, but increases as the inflation pressure increases. However, vehicle manoeuvring behaviour significantly affects the tyre-pavement contact stress distributions. For example, tyre braking/acceleration induces significant longitudinal contact stresses, while tyre cornering causes the peak contact stresses shifting towards one side of the contact patch. The model results provide valuable insights into understanding the realistic tyre-pavement interaction for analysing pavement responses at critical loading conditions.
