| 摘 要： | 分析全钢载重子午线轮胎0°带束层散线缺陷发生的原因，通过有限元仿真方法模拟轮胎成型过程中胎面辊压对0°带束层帘线末端散线位置橡胶的影响。通过优化成型辊压参数，减小0°带束层帘线末端散线位置橡胶的应变，使轮胎0°带束层散线缺陷发生率由0.4%降低到0.18%，在提高轮胎质量的同时也创造了良好的经济效益。

| Abstract: | The reasons for the loose lines in 0° belt of all-steel truck and bus radial tire was analyzed，and the effect of rolling tread on the rubber at the loose line position of the 0° belt cord end was simulated during the tire building process through finite element simulation.By optimizing the building rolling parameters to reduce the strain of the rubber at the 0° belt cord end，the occurrence rate of loose line defects in 0° belt of the tire was reduced from 0.4% to 0.18%，which could not only improve the quality of the tire，but also create good economic benefits. |
