| 中文摘要: |
| 介绍520/85R38 R-1W农业子午线轮胎的设计。结构设计：外直径 1 865 mm，断面宽 482 mm，行驶面宽度 475 mm，行驶面弧度高 35 mm，胎圈着合直径 965 mm，胎圈着合宽度 450 mm，断面水平轴位置（H1/H2） 0.807，胎面采用人字形花纹，花纹深度 51 mm，花纹饱和度 25.2%，花纹周节数 21。施工设计：胎面采用抗刺扎胶料，带束层采用5层2200dtex/2聚酯帘布，胎体采用3层1400dtex/2V1锦纶帘布，采用二次法成型机成型、单模硫化机硫化。成品性能试验结果表明，轮胎的充气外缘尺寸、物理性能和水压爆破性能均符合相应标准及设计要求。 |

| The design of 520/85R38 R-1W agriculture radial tire was introduced.In the structure design，the following parameters were taken：overall diameter 1 865 mm，cross-sectional width 482 mm，width of running surface 475 mm，arc height of running surface 35 mm，bead diameter at rim seat 965 mm，bead width at rim seat 450 mm，maximum width position of cross-section（H1/H2） 0.807，using chevron tread pattern，pattern depth 51 mm，block/total ratio 25.2%，number of pattern pitches 21.In the construction design，the following parameters were taken：using puncture-resistant compound for tread，using 5 layers of 2200dext/2 polyester cord fabric for belts，using 3 layers of 1400dext/2V1 nylon cord fabric for carcass，and using two-step building machine to build tires and single-mold press to cure tires.The test results of the finished tire showed that the inflated perpheral dimension，physical property and hydraulic burst performance of the tire all met the requirements of relative standards and design. |
