| 中文摘要: |
| 采用Ａbaqus软件建立12.00R20全钢载重子午线轮胎的有限元模型。首先在隐式算法下，对轮胎进行充气、静负荷、制动、驱动工况下的接地状态分析，再确定其自由滚动速度，并进行自由滚动分析。然后在显式算法下，模拟轮胎在水平路面自由滚动的动态过程，分析自由滚动过程中轮胎与路面摩擦力及花纹沟体积的变化情况，为胎面花纹磨损机理和花纹噪声的研究及花纹结构设计提供参考。 |

| The finite element model of 12.00R20 truck and bus radial tire was established by using Abaqus software.The contact state was analyzed in implicit algorithm under inflation， static load，braking condition and driving condition.Then the free rolling speed was determined and the free rolling of the tire was analyzed.The dynamic process under free rolling was simulated in explicit algorithm.Then the change of the friction force between tire and road，and the change of groove volume，were analyzed，which provided a useful reference for future research on tread wear and pattern noise，and design of tire pattern. |
