| 中文摘要: |
| 介绍205/55R16 FRC26高性能轮胎的设计。结构设计：外直径 623 mm，断面宽 226 mm，行驶面宽度 170 mm，行驶面弧度高 9.5 mm，胎圈着合直径 400 mm，胎圈着合宽度 192.8 mm，断面水平轴位置（ H/1/H/2） 0.999 8，胎面采用变节距花纹，花纹深度 7.5 mm，花纹饱和度 69.11%，花纹周节数 47。施工设计：胎面采用全分层设计，胎侧采用双复合结构，冠带层采用锦纶66帘线，1#和2#带束层使用3×0.30HT钢丝帘线，胎体采用高模量低收缩聚酯帘线，采用一次法成型机成型和氮气硫化工艺硫化。成品性能试验结果表明，轮胎的充气外缘尺寸、强度性能、耐久性能和高速性能均达到相应设计和企业标准要求。 |
| 英文摘要: |
| The design on 205/55R16 FRC26 high performance tire was described.In the structure design，the following parameters were taken：overall diameter?623 mm，cross-sectional width?226 mm，width of running surface 170 mm，arc height of running surface 9.5 mm，bead diameter at rim seat?400 mm，bead width at rim seat?192.8 mm，maximum width position of cross–section（ H/1/H/2）?0.999 8，the tread adopted variable pitch patter，pattern depth?7.5 mm，block/total ratio?69.11%，and number of pattern pitches?47.In the construction design，the following processes were taken：the tread adopted fully layered design，and the sidewall using double composites structure，nylon 66 cord for crown belt，3×0.30HT steel cord for 1# and 2# belt，high modulus and low shrinkage polyester cord for carcass，and using one-stage building machine to build tires，and nitrogen vulcanization process to cure tires.The test results of finished tire showed that，the inflated peripheral dimention，strength，durability and high speed performance of finished tire met the requirements of corresponding design and enterprise standards. |
