| 中文摘要: |
| 介绍205/55R16 91V轿车子午线轮胎的设计。结构设计：外直径 629 mm，断面宽 221 mm，行驶面宽度 168 mm，行驶面弧度高 7.46 mm，胎圈着合直径 404.2 mm，胎圈着合宽度 185.4 mm，断面水平轴位置（H1/H2） 1.083，胎面花纹为非对称设计的变节距花纹，花纹主沟深度 7.6 mm，花纹饱和度 67%。施工设计：胎面在传统结构基础上加入导电胶，带束层采用2×0.30ST钢丝帘线，胎体采用1100dtex/2聚酯帘线，钢丝圈采用Φ1.2 mm高强度胎圈钢丝，采用一次法成型机成型，硫化采用氮气硫化工艺。成品性能试验结果表明，轮胎的充气外缘尺寸、强度性能、脱圈阻力、高速性能和耐久性能均符合国家标准要求，且轮胎在滚动阻力和噪声方面表现良好。 |
| 英文摘要: |
| The design of 205/55R16 91V passenger car radial tire was described.In the structure design，the following parameters were taken：overall diameter 629 mm，cross-sectional width 221 mm，width of running surface 168 mm，height of running surface 7.46 mm，bead diameter at rim seat 404.2 mm，bead width at rim seat 185.4 mm，maximum width position of cross-section（H1/H2） 1.083，unsymmetrical tread pattern with various lengths，pattern depth 7.6 mm，block/total ratio 67%.In the construction design，the following processes were taken：chimney compound was added in the traditional tread structure，2×0.30ST steel cord for belt layers，1100dtex/2 polyester cord for carcass，Φ1.2 mm high strength wire for bead ring，using one-step building machine to build tire，nitrogen curing process to cure tire.The testing results of finished tires showed that the inflated peripheral dimension，strength，bead unseating resistance，high speed and endurance performance met the requirements of national standards，and the rolling resistance and pass-by noise also achieved good targets. |
