| 中文摘要: |
| 介绍245/70R19.5全钢载重子午线轮胎的设计。依据有限元仿真分析结果，确定结构设计参数如下：外直径 843 mm，断面宽 248 mm，行驶面宽度 225 mm，行驶面弧度高 10 mm，胎圈着合直径 493.5 mm，胎圈着合宽度 203 mm，断面水平轴位置（H1/H2） 0.97，采用横向小块花纹，花纹深度 17.5 mm，花纹饱和度 74.25%，花纹周节数 46。施工设计：胎面采用两方两块设计，胎体采用3×0.24/9×0.225CCHT钢丝帘线，1#—3#带束层采用3×0.20＋6×0.35HT钢丝帘线，4#带束层采用5×0.35HI钢丝帘线；采用一次法机械式成型机成型，液压全自动硫化机硫化。成品性能试验结果表明，成品轮胎的充气外缘尺寸、强度性能和耐久性能均达到国家标准要求。 |
