| 中文摘要: |
| 介绍14.00R24NHS港口专用全钢工程机械子午线轮胎的设计。结构设计：外直径 1 410 mm，断面宽 368 mm，行驶面宽度 320 mm，行驶面弧度高 20 mm，胎圈着合宽度 274 mm，胎圈着合直径 610 mm，断面水平轴位置（H1/H2） 0.739 1，胎面采用块状花纹，花纹深度 64 mm，花纹饱和度 72.2%，花纹周节数 28。施工设计：胎面采用3层结构，胎体采用3＋9＋15×0.225ST钢丝帘线，带束层采用4层结构，其中1#带束层采用3＋9＋15×0.175＋0.15HT钢丝帘线，2#和3#带束层采用3＋9＋15×0.220＋0.15HT钢丝帘线，4#带束层采用3×7×0.20HE钢丝帘线，采用一次法两鼓/三鼓成型机成型，采用蒸锅式硫化机硫化。成品性能试验结果表明，成品轮胎的充气外缘尺寸和物理性能均达到国家标准及相应设计要求。 |
| 英文摘要: |
| Design of 14.00R24NHS all-steel off-the-road radial tire for port was introduced.In the structure design，the following parameters were taken：overall diameter 1 410 mm，cross-section width 368 mm，width of running surface 320 mm，arc height of running surface 20 mm，bead width at rim seat 274 mm，bead diameter at rim seat 610 mm，maximum width position of cross section（H1/H2）
0.739 1，using block pattern for tread，pattern depth 64 mm，block/total ratio 72.2%，and number of pattern pitches 28.In the construction design，the following processes were taken：using three-layer structure for tread，using 3＋9＋15×0.225ST steel cord for carcass，using four-layer structure for belt，3＋9＋15×0.175＋0.15HT steel cord for 1# belt，3＋9＋15×0.220＋0.15HT steel cord for and 2# and 3# belts，3×7×0.20HE steel cord for 4# belt，using one-stage two-drum/three-drum building machine to build tire and steamer curing press to cure tire.The test results of finished tire performance showed that the inflation peripheral dimension and physical properties of the finished tire met the requirements of national standard and corresponding design. |
