| 中文摘要: |
| 采用大型通用有限元仿真分析软件，建立185/70R14轮胎的静态和稳态滚动仿真分析模型，考察不同状态下子午线轮胎内部受力、印痕形状以及外缘尺寸等。结果表明，不同速度下仿真计算半径与实测半径相对误差小于2%；随着速度的提高，印痕形状接近蝴蝶形，胎肩压力增大；肩部带束层骨架材料和带束层端部橡胶材料应变能密度和应力、应变均随速度的提高而增大。 |
| 英文摘要: |
| A simulation analysis model of 185/70R14 tire in static and steady-state rolling was established with large-scale general-purpose FEA software，and the force distribution，footprint shape and overall diameter in different states were investigated.The results showed that the relative error of the radius at different speeds between the calculated and measured values was smaller than 2%；as the speed increased，the footprint shape was more similar to butterfly，the shoulder pressure and strain energy density，stress and strain of belt reinforcement material in shoulder and rubber material of belt ends increased. |
