| 中文摘要: |
| 介绍405/70R18宽基全钢子午线轮胎的设计。结构设计：外直径 1 044 mm，断面宽 400 mm，行驶面宽度 348 mm，行驶面弧度高 12 mm，胎圈着合直径 462 mm，胎圈着合宽度 328 mm，断面水平轴位置（H1/H2 ） 0.75，花纹深度 20 mm，花纹饱和度 45%，花纹周节数 25。施工设计：胎面采用抗切割胶料，胎体采用3＋9×0.22＋0.15钢丝帘线，带束层采用两层3＋8×0.33HT钢丝帘线，钢丝圈采用Φ1.65 mm单根钢丝覆胶缠绕结构，采用一次法成型机成型、蒸锅式双模硫化机硫化。成品性能试验结果表明，轮胎的充气外缘尺寸、耐久性能和水压爆破性能均符合企业标准及设计要求。 |
| 英文摘要: |
| The design of 405/70R18 wide-base all-steel radial tire was introduced.In the structural design，the following parameters were taken：overall diameter 1 044 mm，cross-sectional width 400 mm，width of running surface 348 mm，arc height of running surface 12 mm，bead diameter at rim seat 462 mm，bead width at rim seat 328 mm，maximum width position of cross-section（H1/H2 ） 0.75，pattern depth 20 mm，block/total ratio 45% and number of pattern pitches 25.In the construction design，the following parameters were taken：using cut-resistant compound for tread compound，3＋9×0.22＋0.15 steel cord for carcass，two layers of 3＋8×0.33HT steel cord for belts，Φ1.65 mm compound-coated single steel wire wrapping structure for bead ring，and using single-stage building machine to build tires，steam dome double-mold curing press to cure tires.The test results of the finished tire showed that the inflated peripherial dimension，durability and hydraulic burst performance of the tire all met the requirements of enterprise standards and design. |
