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。
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.
