| 中文摘要: |
| 研究3×0.38ST钢丝帘线在轻型载重子午线轮胎带束层中的应用。结果表明，与2＋2×0.35HT钢丝帘线相比，3×0.38ST钢丝帘线的捻距增大，线密度减小，以其替代2＋2×0.35HT钢丝帘线用于215/65R16LT 8PR轮胎带束层中，成品轮胎的充气外缘尺寸和强度性能满足国家标准要求，耐久和高速性能提高。 |
| 英文摘要: |
| The application of 3×0.38ST steel cord in the belt of light truck and bus radial tire was studied.The results showed that compared with 2＋2×0.35HT steel cord，the 3×0.38ST steel cord exhibited increased pitch and reduced linear density.By replacing 2＋2×0.35HT steel cord with 3×0.38ST steel cord in the belt of 215/65R16LT 8PR tires，the inflated peripheral diameter and strength of the finished tire met the national standard requirements，while the durability and high-speed performance was improved. |
