| 中文摘要: |
| 基于有限元仿真方法，利用Abaqus软件建立225/50R17半钢子午线轮胎的三维有限元模型，研究轮廓参数对轮胎性能的影响。在标准试验条件下，225/50R17半钢子午线轮胎不同结构参数下仿真结果和实际试验结果的趋势具有良好的一致性，仿真结果有效可信。轮廓参数中行驶面宽度（b ）、行驶面弧度高（h h）和断面宽（B ）对轮胎性能的影响为：b 增大，轮胎接地印痕形状系数和径向刚度增大，侧偏刚度减小；h 增大，轮胎滚动阻力系数增大，接地印痕形状系数减小，刚性有所增大；B 增大，轮胎接地印痕形状系数增大，侧偏刚度和回正刚度增大，滚动阻力系数减小。 |

| Based on the finite element simulation method，the three-dimensional finite element model of 225/50R17 steel-belted radial tire was established by using Abaqus software to study the influence of profile parameters on tire performance.Under the standard test conditions，the change tread of simulation results under different structure parameters were in good agreement with that of the actual test results，and the simulation results were effective and reliable.The influences of width of the running surface（b），height of running surface（h） and cross-sectional width（B） were as follows：with the increase of b，the shape coefficient of tire footprint and the radial stiffness increased，and the lateral stiffness decreased.With the increase of h，the rolling resistance coefficient of the tire increased，the shape coefficient of tire footprint decreased，and the rigidity increased.With the increase of B，the shape coefficient of tire footprint increased，the cornering stiffness and return stiffness increased，and the rolling resistance coefficient decreased. |
