中文摘要:
      介绍600/50R22.5农田/公路两用型全钢农业子午线轮胎的设计。结构设计：外直径　1 172 mm，断面宽　620 mm，行驶面宽度　575 mm，行驶面弧度高　18 mm，胎圈着合直径　572 mm，胎圈着合宽度　515 mm，断面水平轴位置（H1/H2）　0.94，胎面采用以横沟为主的横纵混合花纹沟，花纹深度　18 mm，花纹周节数　34，花纹饱和度　53.4%。施工设计：胎面采用单层设计，胎体采用0.25＋6＋12×0.225HT钢丝帘线，3层带束层均采用3＋8×0.33HT钢丝帘线，采用一次法成型机成型，采用活络模硫化机硫化。成品性能试验结果表明，成品轮胎的充气外缘尺寸、耐久性能和高速性能均能达到国家标准及相应设计要求。
英文摘要:
      The design of 600/50R22.5 all-steel agricultural radial tire for farmland and highway was introduced.In the structure design，the following parameters were taken：overall diameter　1 172 mm，cross-section width　620 mm，width of running surface　575 mm，arc height of running surface　18 mm，bead diameter at rim seat　572 mm，bead width at rim seat　515 mm，maximum width position of cross section（H1/H2）　0.94，using the horizontal and vertical mixed pattern grooves mainly composed of horizontal grooves for tread，pattern depth　18 mm，number of pattern pitches　34，and block/total ratio　53.4%.In the construction design，the following processes were taken：using single compound design for tread，using 0.25＋6＋12×0.225HT steel cord for carcass，3＋8×0.33HT steel cord for 3 layers of belts，using one-stage building machine to build tires and dual-mode curing press to cure tires.The test results of finished tire showed that the inflation peripheral dimension，durability and high-speed performance of the finished tire met the requirements of national standard and corresponding design.
