摘　　要：介绍AT27×12.00-14 8PR半子午化全地形轮胎的设计。结构设计:外直径670mm,断面宽310mm,行驶面宽度274mm,行驶面弧度高0mm,胎圈着合直径352.8mm,胎圈着合宽度254mm,花纹深度20mm,花纹周节数20,花纹饱和度28.5%。施工设计:胎面采用两方三块结构,胎体采用2层1400dtex/2锦纶6浸胶帘布,缓冲层采用2层2100dtex/3锦纶6浸胶帘布;采用胶囊反包成型机成型、胶囊硫化机硫化。成品轮胎试验结果表明,轮胎的充气外缘尺寸、强度性能、耐久性能和速度性能均符合相应设计和国家标准要求,静负荷性能满足使用要求。The design of AT27×12.00-14 8PR semi-radial all terrain tire was described.In the structure design,the following parameters were taken：overall diameter 670 mm,cross-sectional width 310 mm,width of running surface 274 mm,height of running surface 0mm,bead diameter at rim seat 352.8mm,bead width at rim seat 254 mm,pattern depth 20 mm,total number of pitches 20,and block/total ratio 28.5%.In the construction design,the following processes were taken：two-formula and three-piece extruded tread,2layers of 1400dtex/2dipped nylon 6cord for carcass ply,2layers of 2100dtex/3dipped nylon 6cord for breaker ply;bladder turn-up building machine for building tires,and using bladder curing press for curing.It was confirmed by the tests of finished tires that the inflated peripheral dimension,strength performance,endurance performance and speed performance met the requirements of relative design and national standard,and the static load performance met the using requirement.
