摘　　要：研究混纺材料冠带层对轿车轮胎主、客观性能的影响,并通过单变量分析方法探究冠带层采用混纺材料的优缺点。结果表明:冠带层材料由锦纶调整为混纺材料可使轮胎的接地印痕面积增大,印痕趋于矩形,侧偏刚度和F函数值增大;轮胎主观性能评价的基础转向性能和操纵性能提升,但滚动阻力系数增大。The effect of blended material crown belt on the subjective and objective performance of passenger car tires was studied,and the advantages and disadvantages of blended material for crown belt were explored through univariate analysis method.The results showed that the adjustment of crown belt material from nylon to blended material could increase the tire footprint area,the footprint tended to be rectangular,the cornering stiffness and F function value increased,and the basic steering performance and handling performance of the subjective performance evaluation of the tire were improved,but the rolling resistance coefficient increased.
