| 中文摘要: |
| 用有限元分析软件Abaqus模拟分析不同胎压下子午线轮胎胎侧裂口的扩展情况。结果表明：随着胎压增大，J积分最大值增大；当胎压较小时，J积分最大值出现在裂口尖端方向0°附近，J积分最大值近似线性增长；当胎压较大时，裂口扩展方向发生变化，J积分最大值的增长速度明显放缓并趋于极值。 |
| 英文摘要: |
| The crack propagation of radial tire sidewall under different tire pressures was simulated by finite element analysis software Abaqus.The results showed that as the tire pressure increased，the maximum value of J integral increased.When the tire pressure was low，the maximum value of J integral appeared near the direction of the crack tip 0° and the maximum value of J integral increased approximately linearly.When the tire pressure was high，the crack propagation direction changed，and the growth rate of the J integral value slowed down and J integral value tended to the extreme value. |
