| 中文摘要: |
| 以轿车子午线轮胎（简称轮胎）为研究对象，建立轮胎-转鼓有限元模型，并采用隐式-显式仿真分析方法对轮胎瞬态冲击特性进行仿真研究。结果表明：轮胎从较低速度向较高速度转变时，对障碍条的包覆行为存在由完全包覆向非完全包覆转移的现象；随着轮胎速度的增大，轮胎径向力最大幅值变化趋势为增大-减小-增大-减小，周向力最大幅值变化趋势与之相反；径向力衰减特性是轮胎固有属性，不随轮胎速度的变化而变化；在较低速度下负荷越小的轮胎行驶舒适性越好，在中等速度下适量负荷可以保证轮胎行驶舒适性最好，在较高速度下负荷越大的轮胎行驶舒适性越好。 |

| Taking the passenger car radial tire（refer to as the tire） as the research object，a tire-drum finite element model was constructed，and the transient impact characteristic of the tire was simulated and studied using the implicit-explicit simulation analysis method.The results showed that when the tire speed changed from the lower to the higher，there was a phenomenon of transition from complete envelopment to incomplete envelopment of the cleat.As the tire speed increased，the trend of the maximum amplitude change of the radial forces of the tire was increasing-decreasing-increasing-decreasing，while the trend of the maximum amplitude change of the circumferential forces of the tire was opposite.Radial force attenuation characteristic was inherent properties of the tire，and it did not vary with changes of tire speed.At lower speeds，the load was smaller，the impact comfort of the tire was better.At moderate speeds，an appropriate amount of load could ensure the best impact comfort of the tire.At higher speeds，the load was greater，the impact comfort of the tire was better. |
