| 中文摘要: |
| 介绍12.00R20 18PR全钢载重子午线轮胎轻量化设计。结构设计：外直径 1 120 mm，断面宽 316 mm，行驶面宽度 230 mm，行驶面弧度高 7.9 mm，断面水平轴位置（H1/H2） 0.932 8，花纹深度 16 mm，花纹饱和度 69.76％，花纹周节数 49。施工设计：胎面采用双复合挤出机挤出，胎体采用0.25＋（6＋12）×0.225HT钢丝帘线，1#和2#带束层采用4＋6×0.30HT钢丝帘线，3#带束层采用3×4×0.22HE钢丝帘线，0°带束层采用3×7×0.20HE钢丝帘线，钢丝圈采用 Φ1.65 mm高强度胎圈钢丝，采用三鼓成型机成型、B型双模翻转式热板硫化机硫化。成品轮胎试验结果表明，轮胎的充气外缘尺寸、强度性能和耐久性能均达到相关设计和国家标准要求，胎圈耐久性能达到企业标准要求。 |

| The lightweight design of 12.00R20 18PR truck and bus radial tire was introduced.In structure design，the following parameters were taken：overall diameter 1 120 mm，cross-sectional width 316 mm，width of running surface 230 mm，arc height of running surface 7.9 mm，maximum width position of cross-section（H1/H2） 0.932 8，pattern depth 16 mm，block/total ratio?69.76%，and number of pattern pitches?49.In construction design，the following processes were taken：co-extruded tread，0.25＋（6＋12）×0.225HT steel cord for carcass，4＋6×0.30HT steel cord for 1# and 2# belt，3×4×0.22HE steel cord for 3# belt，3×7×0.20HE steel cord for 0° belt，Φ1.65 mm high strength steel for bead wire，and using three-drum building machine to build tire and type B double mold hot plate curing press to cure tire.It was confirmed by the finished tire test that，the inflated peripheral dimension，strength performance and endurance performance reached the requirements of design and national standards，and the bead endurance performance reached the requirements of enterprise standard. |
