| 中文摘要: |
| 介绍265/40R20 UHP轮胎的设计。结构设计：外直径 716 mm，断面宽 282 mm，行驶面宽度 220 mm，行驶面弧度高 10.6 mm，胎圈着合直径 508 mm，胎圈着合宽度 262 mm，断面水平轴位置（H1/H2） 1.05，采用UHP轮胎专用TH201花纹，优化花纹节距排列。施工设计：胎体使用2层1440dtex/2 DSP聚酯帘布高反包结构，带束层采用2＋2×0.30HT钢丝帘线，矩形钢丝圈结构；采用SOT一次法成型机成型；双模液压硫化机硫化。成品性能试验结果表明：成品轮胎充气外缘尺寸、强度性能、脱圈阻力、耐久及高速性能符合相应国家标准和企业标准要求，滚动阻力和噪声性能达到欧盟标签法限值要求，装车路试结果达到了设计目标。 |
| 英文摘要: |
| The design on 265/40R20 UHP radial tire was described.In structure design，the following parameters were taken：overall diameter 716 mm，cross-sectional width 282 mm，width of running surface 220 mm，arc height of running surface 10.6 mm，bead diameter at rim seat 508 mm，bead width at rim seat 262 mm，maximum width position of cross-section （H1/H2） 1.05，and special tread pattern TH201 for UHP tire with optimized pitch arrangement．In construction design，the following processes were taken：2 layers of 1440dtex/2 DSP polyester cords for carcass with high turn-up，2＋2×0.30HT steel cord for belt ply，wrapped rectangle bead，one-stage SOT building machine to build-up tires and hydraulic curing press to cure tires．It was confirmed by the finished tire test that，the inflated peripheral dimension，strength performance，bead unseating resistance，endurance and high speed performance met the requirements of corresponding national and enterprise standards，rolling resistance and rolling noise met the requirements of EU Label act，and the tire performance in vehicle test reached design objective. |
