| 中文摘要: |
| 介绍7.00－15 12PR工业车辆轮胎的设计。结构设计：外直径 744 mm，断面宽 172 mm，行驶面宽度 150 mm，行驶面弧度高 10 mm，胎圈着和直径 386 mm，胎圈着和宽度 140 mm，断面水平轴位置（H1H2） 0.808，采用SD6000花纹，花纹深度 14 mm，花纹饱和度 72%，花纹周节数 28。施工设计：胎面采用三方四块结构，胎体采用4层高强度2100dtex/2V1和2层高强度2100dtex/2V2锦纶6浸胶帘布，缓冲层采用2层1400dtex/2锦纶6浸胶帘布，采用胶囊反包自动成型机成型，四立柱硫化机硫化。成品性能试验结果表明，成品轮胎充气外缘尺寸符合客户要求，物理性能符合国家标准要求。 |
| 英文摘要: |
| The design on 7.00－15 12PR industrial vehicle tire was described．In the structure design，the following parameters were taken：overall diameter 744 mm，cross-sectional width 172 mm，width of running surface 150 mm，arc height of running surface 10 mm，bead diameter at rim seat 386 mm，bead width at rim seat 140 mm，maximum width position of cross–section（H1/H2） 0.808，SD6000 tread pattern，pattern depth 14 mm，block/total ratio 72%，and number of pattern pitches 28.In the construction design，the following processes were taken：three-formula and four-piece structure for tread，4 layers of high strength 2100dtex/2V1 and 2 layers of high strength 2100dtex/2V2 nylon 6 dipped cord for carcass，2 layers of 2100dtex/2 nylon 6 dipped cord for breaker ply；using bladder turn-up automatic building machine to build tire and four pillar curing press to cure tire.It was confirmed by the finished tire test that，the inflated peripheral dimension met the requirment of customer，and the physical properties met the requirements of the national standard. |
