摘　　要：介绍235/45ZR1898W仿生轿车子午线轮胎的设计。结构设计:外直径666 mm,断面宽239 mm,行驶面宽度208 mm,行驶面弧度高9.4 mm,胎圈着合直径460.4 mm,胎圈着合宽度216 mm,断面水平轴位置(H1/H2)0.9108,花纹形状模仿兰科植物叶片形状,采用变节距设计,花纹深度7.5 mm,花纹饱和度71.7%,花纹周节数72。施工设计:胎面采用耐磨、低滚动阻力配方,胎体采用1层1400dtex/3改性锦纶浸胶帘布,2层带束层均采用3×0.30HT钢丝帘线,采用一次法成型机成型、双模液压硫化机硫化。成品轮胎试验结果表明,轮胎的充气外缘尺寸、强度性能、脱圈阻力、耐久及低压耐久性能和高速性能均达到国家标准和设计要求,抗湿滑性能和滚动阻力分别达到欧盟标签法B级和C级要求,噪声测试结果为72 dB,产品取得了欧盟标签法第2阶段认证。The design on 235/45ZR1898W bionic passenger car radial tire was described.In the structure design,the following parameters were taken:overall diameter 666 mm,width of cross-section 239 mm,width of running surface 208 mm,arc height of running surface 9.4 mm,bead diameter at rim seat 460.4 mm,bead width at rim seat 216 mm,maximum width position of cross-section(H1/H2)0.9108,bionic tread pattern based on orchid leaf,variable pitch design,pattern depth 7.5 mm,block/total ratio 71.7%,and number of pattern pitches 72.In the construction design,the following processes were taken:wear-resistant and low rolling resistant formula for tread,1 layer of 1400dtex/3 dipped modified nylon cord for carcass,3×0.30HT steel cord for both layers of belt,using one-stage building machine to build tire,and dual-mold hydraulic vulcanizer to cure tire.It was confirmed by the finished tire test that,the inflated peripheral dimension,strength performance,bead unseating resistance,endurance,low inflation pressure endurance,and high-speed performance met the requirements of national standards and the design targets.The wet skid resistance and rolling resistance met the requirements of level B and level C of the EU labeling method,respectively,and the noise test result was 72 dB.The product was certified by the secondstage EU tire labelling regulation.
