| 中文摘要: |
| 介绍绿色高里程全钢载重子午线轮胎的设计研发。使用TDSS轮胎设计与仿真系统对轮胎的接地印痕和压力分布、稳态温度场分布和花纹块刚度进行仿真优化。结构设计：外直径 1 082 mm，断面宽 290 mm，行驶面宽度 240 mm，行驶面弧度高 6.5 mm，采用3种节距设计，节距总数 80，花纹节距比 0.91∶1∶1.1，花纹深度 17.5 mm，花纹饱和度 78.1%。施工设计：胎面采用定速、定量、稳定的挤出方式，胎冠胶为配方和工艺优化的高耐磨性能胶料，胎体采用3＋9＋15×0.175＋0.15钢丝帘线，带束层采用4层带束层结构，1#和4#带束层分别采用3×0.20＋6×0.35HT和5×0.35HI钢丝帘线，2#和3#带束层采用3＋8×0.33HT钢丝帘线。成品轮胎性能试验结果表明，轮胎充气外缘尺寸、强度性能、耐久性能和高速性能均符合国家或企业标准要求。 |
| 英文摘要: |
| The design and development of green high mileage truck and bus radial tire was introduced.The tire footprint and pressure distribution，steady-state temperature field distribution and block stiffness were simulated and optimized using the TDSS tire design and simulation system.In the structure design，the following parameters were taken：overall diameter 1 082 mm，cross-sectional width 290 mm，width of running surface 240 mm，arc height of running surface 6.5 mm，using three pitch design，total number of pitches 80，pattern pitch ratio 0.91∶1∶1.1，pattern depth 17.5 mm，block/total ratio 78.1%.In construction design，the following processes were taken：a constant speed，quantitative and stable extrusion method for tread was adopted，the crown compound was a high wear-resistant compound with optimized formula and process，the carcass adopted 3＋9＋15×0.175＋0.15 steel cord，and the belt layer adopted 4 layers，1# and 4# belt used 3×0.20＋6×0.35HT and 5×0.35HI steel cord，respectively，2# and 3# belt used 3＋8×0.33HT steel cords.The test results of finished tire showed that the tire inflated peripheral dimension，strength，endurance and high-speed performance all met the requirements of national or enterprise standards. |
