| 中文摘要: |
| 将车辆简化为单自由度振动模型，采用ABAQUS有限元分析软件建立11.00R20全钢载重子午线轮胎在水平路面上滚动的三维有限元模型，模拟轮胎与路面障碍的碰撞过程，并用显式有限元程序分析轮胎在碰撞过程中的受力、变形和接地压力分布等力学特性。结果表明，碰撞过程对轮胎力学特性有很大影响。 |
| 英文摘要: |
| By simplifying the vehicle as a single-freedom vibration model，a 3D finite element analysis（FEA） model of 11.00R20 TBR tire rolling on road was established by ABAQUS FEA software to simulate the tire-obstacle collision process，and the mechanical properties such as the force，deformation and pressure distribution in ground-contact area were analyzed by explicit FEA method.The results showed that the collision process had significant influence on the mechanical properties of the tire. |
