| 中文摘要: |
| 以子午线轮胎11.00R20为例，考虑轮胎变形的几何非线性、材料非线性以及轮胎与地面、轮胎与轮辋的大变形非线性接触等，利用ABAQUS软件建立了轮胎与地面接触的三维有限元模型。研究了充气压力、下沉量、行驶速度、轮胎与地面的摩擦因数和侧偏角等参数对轮胎接地特性的影响。并模拟了轮胎的侧偏运动，研究了垂直负荷、充气压力和轮胎与地面的摩擦因数等参数对轮胎侧偏特性的影响。结果表明，这些参数对轮胎的接地特性和侧偏特性有一定的影响，从而为轮胎设计和应用提供参考。 |

| Taking radial tire 11.00R20 as an example，a three-dimensional finite element model of tire-ground contact was established by using ABAQUS software，considering the geometric nonlinearity，material nonlinearity and large deformation in nonlinear contact between tire and ground and between tire and rim.The effects of parameters such as inflation pressure，deformation，driving speed，friction coefficient between tire and ground and slip angle on tire-ground contact characteristics were studied.The cornering movement of the tire was simulated，and the effects of parameters such as vertical load，inflation pressure and friction coefficient between tire and ground on cornering properties were investigated.The results showed that these parameters had impact on the contact characteristics and cornering properties of tire and provided a useful reference for design and application of tire. |
