中文摘要:
      介绍港口跨运机用16.00R25 IND-4 ★★★无内胎全钢工程机械子午线轮胎的设计。结构设计：外直径　1 502 mm，断面宽　422 mm，行驶面宽度　380 mm，行驶面弧度高　21 mm，胎圈着合直径　630 mm，胎圈着合宽度　298 mm，断面水平轴位置（H1/H2）　0.8，采用条形花纹设计，花纹深度　50 mm，花纹饱和度　86.3%，花纹周节数　32。施工设计：胎面采用冷喂料挤出、缠绕法成型，胎体采用7×7×0.22＋0.15HT钢丝帘线，1#带束层采用3＋9＋15×0.175＋0.15钢丝帘线，2#和3#带束层采用3＋9＋15×0.22＋0.15，4#带束层采用3×7×0.20HE钢丝帘线，采用一次法两鼓成型机成型、B型硫化机硫化。成品轮胎性能试验结果表明，轮胎充气外缘尺寸、物理性能和耐久性能均符合相应设计和国家标准要求。
英文摘要:
      The design on 16.00R25 all-steel off-the-road radial tire for straddle carrier was described.In the structure design，the following parameters were taken：overall diameter　1 502 mm，cross-sectional width　422 mm，width of running surface　380 mm，arc height of running surface　21 mm，bead diameter at rim seat　630 mm，bead width at rim seat　298 mm，maximum width position of cross-section（H1/H2）　0.8，using rib pattern design，pattern depth　50 mm，block/total ratio　86.3%，and the number of pattern pitches　32.In the construction design，the following processes were taken：cold-feeding extrusion and winding for tread，7×7×0.22＋0.15HT steel cord for carcass ply，3＋9＋15×0.175＋0.15 steel cord for 1# belt，3＋9＋15×0.22＋0.15 steel cord for 2# and 3# belt，3×7×0.20HE steel cord for 4# belt，using one stage double-drum builder to built tires and B type press to cure tires.It was confirmed by the test of the finished tire that the inflated peripheral dimension，physical property and endurance met the requirements of relative design and national standard.
