| 中文摘要: |
| 对比研究3＋8×0.22ST与3＋9×0.22＋0.15HT钢丝帘线在全钢载重子午线轮胎胎体中的应用性能。结果表明：与3＋9×0.22＋0.15HT钢丝帘线相比，3＋8×0.22ST钢丝帘线的直径和线密度减小，破断力相当，渗胶性能提高；与采用3＋9×0.22＋0.15HT钢丝帘线生产的轮胎相比，采用3＋8×0.22ST钢丝帘线生产的轮胎的高速性能、耐久性能和刚度相当，滚动阻力降低，同时轮胎质量减小，生产成本降低。 |
| 英文摘要: |
| The application properties comparison of 3＋8×0.22ST and 3＋9×0.22＋0.15HT steel cord in the carcass of truck and bus radial tire was studied.The results showed that compared with 3＋9×0.22＋0.15HT steel cord，the cord diameter and linear density of 3＋8×0.22ST steel cord were decreased，the breaking force was equivalent and the rubber permeability was improved.Compared with the tires produced with 3＋9×0.22＋0.15HT steel cord，the high-speed performance，durability and stiffness of the tires produced with 3＋8×0.22ST steel cord were equivalent，the rolling resistance was reduced，while the tire weight was decreased，and production cost was reduced. |
