建立了三维轮胎-路面相互作用有限元模型（FEM），并对其进行了标定和验证。首先，使用有限元程序ADINA，根据轮胎制造商报告的轮胎特性，建立了载重子午线轮胎的三维模型。在此基础上，建立了轮胎与路面的接触群，从而建立了完整的轮胎-路面相互作用模型。轮胎模型特性的基础上，从一个子午线卡车轮胎的测量负荷-挠度曲线进行校准。然后，通过比较预测的接触应力与实际载重子午线轮胎的实测应力，验证了该模型。接触应力分析进行评估轮胎在不同水平的正常负载和充气压力下的响应。观察到预测和测量的接触应力之间的良好对应关系。这项工作似乎表明，轮胎制造商报告的轮胎结构和几何信息，沿着测量的载荷-挠度数据，可以用来开发三维模型，预测轮胎-路面界面应力及其对路面性能的影响。
A three-dimensional tire–pavement interaction finite element model (FEM) was developed, calibrated, and validated. First, a three-dimensional model of a radial truck tire was developed on the basis of tire characteristics reported by tire manufacturers using the finite element program ADINA. Contact groups between tire and pavement surfaces were then created, thus establishing a complete tire–pavement interaction model. Tire model properties were calibrated on the basis of measured load–deflection curves from one radial truck tire. The model was then validated by comparing predicted contact stresses with measured stresses from the actual radial truck tire. Contact stress analysis was conducted to evaluate tire responses under different levels of normal load and inflation pressure. Excellent correspondence between predicted and measured contact stresses was observed. This work appears to indicate that tire structure and geometry information reported by tire manufacturers, along with measured load–deflection data, can be used to develop three-dimensional models to predict tire–pavement interface stresses and their effects on pavement performance.
