| 中文摘要: |
| 针对市场上12.00R24全钢子午线轮胎破坏集中于下模的问题，通过有限元仿真分析轮胎上下模结构差异对轮胎性能的影响。结果表明，上下模的不对称性会导致轮胎单侧性能降低，进而增加破坏风险。通过提高成品轮胎断面的放行标准，严格控制不对称性，轮胎的使用寿命明显延长，可靠性显著提升，市场上轮胎破坏位置不再集中于单侧。 |
| 英文摘要: |
| Regarding the prevalent failure issue concentrated in the lower mold of 12.00R24 all-steel radial tires in the market，through the finite element simulation，the influence of structural differences between the upper and lower mold sections on tire performance was analyzed.The results revealed that the structural asymmetry led to performance degradation on one side of the tire，consequently increasing its risk of failure.By Tightering the approval criteria of the cross-sectional of the finished tires to strictly control its asymmetry，the service life of the tire was prolonged，the reliability was significantly improved，and the failures of the tire in the market were no longer primarily localized to one side. |
