| 中文摘要: |
| 研究7×（3＋9×0.245）＋0.20HT钢丝帘线在巨型工程机械子午线轮胎胎体中的应用。结果表明：与7×（3＋9＋15×0.175）＋0.20HT钢丝帘线相比，7×（3＋9×0.245）＋0.20HT钢丝帘线的直径和覆胶帘布厚度减小，以其替代7×（3＋9＋15×0.175）＋0.20HT钢丝帘线用于30.00R51巨型工程机械子午线轮胎胎体，可以满足生产工艺要求，提高轮胎的耐久性能，同时可降低生产成本。 |
| 英文摘要: |
| The application of 7×（3＋9×0.245）＋0.20HT steel cord in the carcass of giant off-the-road radial tire was investigated.The results showed that，compared with 7×（3＋9＋15×0.175）＋0.20HT steel cord，7×（3＋9×0.245）＋0.20HT steel cord possessed smaller diameter and thickness of coating cord.Using 7×（3＋9×0.245）＋0.20HT steel cord instead of 7×（3＋9＋15×0.175）＋0.20HT steel cord in the carcass of 30.00R51 giant off-the-road radial tire，the production process could meet the requirements，the endurance of the finished tire was improved，and the product cost was reduced. |
