| 中文摘要: |
| 介绍11.00R20 18PR矿山用全钢载重子午线轮胎的设计。结构设计：外直径 1 079 mm，断面宽 286 mm，行驶面宽度 230 mm，胎圈着合直径 511 mm，花纹深度 20 mm，花纹饱和度 70.3%，花纹沟采用V型开放设计。施工设计：胎面胶采用NR/SBR/BR优化配方，胎体采用3+8×0.33HT钢丝帘线，带束层采用3层带束层加2层0°带束层结构。成品轮胎试验结果表明，轮胎充气外缘尺寸、物理性能、强度性能、耐久性能及速度性能均符合相应设计和标准要求。 |
| 英文摘要: |
| The design of 11.00R20 18PR mine TBR tire was described.In structure design，the following parameters were taken：overall diameter 1 079 mm，cross sectional width 286 mm，width of running surface 230 mm，bead diameter at rim seat 511 mm，pattern depth 20 mm，block/groove ratio 70.3%，with the design of V groove.In construction design，the following processes were taken：NR/SBR/BR optimized formulations for tread，3+8×0.33HT steel cord for carcass ply，3 ply belts and 2 ply 0° belts for belt ply.The inflated overall dimension，physical properties，strength performance，endurance performance and speed performance of finished tire met the requirements in the relative design and standards. |
