| 中文摘要: |
| 研究3＋8×0.33ST钢丝帘线真空载重子午线轮胎带束层中的应用。结果表明，采用3＋8×0.33ST钢丝帘线替代3＋9＋15×0.22W钢丝帘线用于13R22.5真空载重子午线轮胎带束层中，成品轮胎的外缘尺寸符合国家标准要求，耐久性能和高速性能提高，轮胎接地印痕矩形率更大，接地压力分布更均匀，轮胎质量减小，成本降低。 |
| 英文摘要: |
| The application of 3＋8×0.33ST steel cord in belt of vacuum truck and bus radial tire was studied.The results showed that，using 3＋8×0.33ST steel cord replace 3＋9＋15×0.22W steel cord in belt of 13R22.5 vacuum truck and bus radial tire，the inflated peripheral dimension of the finished tire met the requirements of national standards，the durability and high-speed performance were improved，the rectangular rate of tire footprint was increased，the ground-contact pressure distribution was more uniform，the tire weight and the cost were reduced. |
