| 中文摘要: |
| 基于Abaqus软件，在现有规格基础上对205/75R17.5 14PR全钢轻型载重汽车驱动轮胎进行优化设计。结构设计：外直径 752 mm，断面宽 205 mm，行驶面宽度 180 mm，行驶面弧度高 5.5 mm，胎圈着合宽度 172 mm，胎圈着合直径 442 mm，断面水平轴位置（H1/H2） 0.82，胎面采用变节距设计，花纹深度 14 mm，花纹饱和度 68.8%，花纹周节数 45。施工设计：胎面采用2层结构，胎体采用3＋9×0.22W钢丝帘线，带束层采用3层结构，其中1#和2#带束层均采用0.37＋6×0.32ST钢丝帘线，3#带束层采用1×5×0.30HI钢丝帘线，采用一次法两鼓成型机成型和蒸锅式硫化机硫化。成品性能试验结果表明，成品轮胎的充气外缘尺寸、滚动阻力和质量均满足市场需求。 |
