| 中文摘要: |
| 以超高强度0.22+18×0.20ST钢丝帘线替代0.25+(6+12)×0.225HT钢丝帘线应用于全钢载重子午线轮胎胎体。试验结果表明：与0.25+(6+12)×0.225HT钢丝帘线相比，0.22+18×0.20ST钢丝帘线直径和线密度减小，破断力和刚度降低；以0.22+18×0.20ST钢丝帘线替代0.25+(6+12)×0.225HT钢丝帘线后，成品轮胎的外缘尺寸、强度性能、耐久性能和速度性能均满足设计和相关标准要求，且轮胎质量和成本减小。 |
| 英文摘要: |
| Super high strength 0.22+18×0.20ST steel cord was applied in the carcass of truck and bus radial tire and compared with 0.25+(6+12)×0.225HT steel cord.The test results showed that，compared with 0.25+(6+12)×0.225HT steel cord，0.22+18×0.20ST steel cord possessed smaller diameter and linear density，and lower breaking strength and stiffness.Using 0.22+18×0.20ST steel cord to replace 0.25+(6+12)×0.225HT steel cord in the carcass，the inflated peripheral dimension，strength performance，endurance performance and speed performance of the tires met the requirements of corresponding design and standards，and the weight and cost of tires decreased. |
