| 中文摘要: |
| 讨论骨架材料的规格、结构分布及工艺控制对全钢载重子午线轮胎性能的影响。胎体帘布采用带有外缠丝的3+9+15×0.22+0.15规格钢丝、胎体帘线密度在450～650 根·m-1范围内（帘线直径大于1.2 mm）以及胎体反包端点在成品外轮廓曲线的第2或3条装配线上等措施均有利于保证胎体强度；合理设计带束层结构，端点与胎侧肩部花纹距离取10 mm左右有利于消除应力过度集中；采用钢丝增强带有利于提高胎圈刚性。 |
| 英文摘要: |
| The influence of the size and structural distribution of reinforcing material on the performance of BTR tire was investigated.The results showed that the carcass strength could be ensured by using 3+9+15×0.22+0.15 steel cord with outer wrapping filament,density of 450～650 ends·m-1 and diameter greater than 1.2 mm,and placing the turn-up end on the second or third fitting line of finished tire;the stress concentration in should area could be eliminated by designing the belt structure resonably and taking the distance from the belt ends to the tread patterns in shoulders of about 10 mm;and the bead stiffness could be increased by using the steel cord reinforcing strip. |
