| 中文摘要: |
| 对全钢载重子午线轮胎胎面花纹沟底裂口风险进行有限元分析，优化预测花纹沟底裂口的有限元分析指标。结果表明，采用轮胎非接地侧沟底Mises应力可以表征花纹沟底裂口风险。在采用相同花纹条件下选取12R22.5，275/70R22.5，385/65R22.5，315/60R22.5，445/45R19.5规格轮胎进行仿真分析发现，随着轮胎断面高宽比减小，花纹沟底应力增大，花纹沟底裂口风险提高。比较不同方案花纹沟底应力大小时，需保持相同网格尺寸，花纹沟底位置网格尺寸控制在1.0 mm以下为宜。 |

| A finite element analysis（FEA） was conducted on the risk of tread pattern groove bottom cracks in all-steel truck and bus radial tires to optimize the FEA criteria for predicting the groove bottom cracks.The results indicated that the Mises stress on the non-contact side of the tire’s groove bottom could characterize the risk of groove bottom cracks.Under identical tread patterns，simulation analyses were performed on tires with specifications of 12R22.5，275/70R22.5，385/65R22.5，315/60R22.5，and 445/45R19.5，and it was found that as the cross-section aspect ratio of the tire decreased，the stress on the groove bottom increased，leading to a higher risk of groove bottom cracks.When comparing the stress levels on the groove bottom across different schemes，it was essential to maintain the same mesh size，with the mesh size at the groove bottom preferably controlled below 1.0 mm. |
