中文摘要:
      以165/75R13和185/65R14两种常用规格轮胎为例，利用数值模拟法研究用芳纶替代钢丝作带束层或锦纶作冠带层骨架材料对高速自由滚动工况下轮胎力学性能的影响。结果表明：将芳纶用于带束层，在减小轮胎质量的同时不降低使用性能；芳纶冠带层轮胎在承载能力、耐久性和强度等方面与现有轮胎及芳纶带束层轮胎相比都有显著优势，且轮胎规格越大，芳纶冠带层对轮胎性能的改善效果越明显。
英文摘要:
      Taking two normal tires，165/75R13 and 185/65R14，as examples，the effect of using aramid fiber to replace steel cord in the belt ply and nylon fiber in the cap ply on the mechanical properties of tires under high speed free rolling condition was studied by using numerical simulation method.The results showed that，aramid fiber belt ply reduced tire weight while the tire performance was maintained.With aramid fiber cap ply，the load carrying capacity，durability and strength of the tire were better than conventional tire and the tire with aramid fiber belt ply，and the benefit was more significant when the tire size was larger.
