| 中文摘要: |
| 对12.00-20 18PR矿用轮胎进行优化设计，以提高轮胎品质。优化设计措施为：行驶面宽度取235 mm，行驶面弧度高取22 mm，断面水平轴位置(H1/H2)取0.837 8，胎面基部胶宽度由500 mm减至390 mm，厚度由12 mm增至15.5 mm，胎面胶宽度由440 mm增至470 mm，胎面厚度由24 mm增至31 mm，胎肩厚度由27 mm减至20 mm，胎圈由双钢丝圈结构调整为三钢丝圈结构，胎体成型方式由4－4－2调整为3－3－2－2，调整胎体帘布反包高度。成品性能试验结果表明，优化后轮胎的充气外缘尺寸和物理性能均符合国家标准要求，耐久性能大幅提高。 |

| The design of 12.00-20 18PR tire for mining vehicle was optimized，in order to improve the quality of tires.The width of running surface was 235 mm，the height of running surface was 22 mm，and the maximum width position of cross section(H1/H2) was 0.837 8.The width of lower tread was decreased from 500 mm to 390 mm，the thickness of lower tread was increased from 12 mm to 15.5 mm，the width of tread was increased from 440 mm to 470 mm，the thickness of tread was increased from 24 mm to 31 mm，the thickness of the tire shoulder was decreased from 27 mm to 20 mm，and the bead was modified from two bead wires to three bead wires.The building process of carcass was modified from 4－4－2 to 3－3－2－2，and the turn up height of carcass ply was adjusted.It was confirmed by the tests of the finished tire that，the peripheral dimension and physical properties met the requirements of national standards，and the endurance performance was significantly improved. |
