| 中文摘要: |
| 介绍205/50R16 91W高性能轿车子午线轮胎的设计。结构设计：外直径 610 mm，断面宽 217 mm，行驶面宽度 176 mm，行驶面弧度高 8 mm，胎圈着合直径 404.6 mm，胎圈着合宽度 178 mm，断面水平轴位置（H1/H2） 0.96，采用非对称性有向花纹设计，花纹深度 8.2 mm，花纹周节数 35，花纹饱和度 70%。施工设计：胎面采用三方四块结构，胎体采用1400dtex/2锦纶66浸胶帘布，带束层采用2+2×0.3HT钢丝帘线；采用一次法成型机成型，双模定型硫化机硫化。成品轮胎性能试验结果表明，轮胎的充气外缘尺寸、强度性能和脱圈阻力均符合相应设计和国家标准要求，耐久性能、低气压性能和高速性能符合企业标准要求。 |
| 英文摘要: |
| A design of 205/50R16 91W high performance passenger car radial tire was described.In structure design，the following parameters were taken：overall diameter 610 mm，cross sectional width 217 mm，width of running surface 176 mm，height of running surface 8 mm，bead diameter at rim seat 404.6 mm，bead width at rim seat 178 mm，cross-sectional level ratio（H1/H2） 0.96，with the design of unsymmetrical directed pattern，pattern depth 8.2 mm，pattern circular pitch 35，block/groove ratio 70%.In construction design，the following processes were taken：three-formula and four-piece extruded tread，1400dtex/2 dipped nylon 66 cord for carcass ply，2+2×0.3HT steel cord for belt ply；using single stage building machine to build tires，and using double mold shaping curing press to cure tires.It was confirmed by the tests of finished tires that，the inflated peripheral dimension，strength performance and bead unseating resistance met the requirements of relative design and national standard，and the endurance performance，low air pressure and high speed performance met the requirements of enterprise standard. |
