中文摘要:
      采用Abaqus有限元分析软件，研究芳纶纤维在子午线轮胎带束层和冠带层中的应用效果。结果表明：轮胎带束层采用芳纶纤维，第1和第2带束层轴向、横向对称面内周向应力以及带束层端点周向应力均有不同程度下降，提高了轮胎强度和承载能力；冠带层采用芳纶纤维，轴向接地中心线上冠带层肩部应力显著降低，冠带层端点周向应力大幅减小，应力分布均匀性显著提高，能够降低轮胎骨架材料端点破坏的可能性。
英文摘要:
      The application of aramid fibers in belt ply and cap ply of radial tire were studied with finite element analysis software Abaqus.The results showed that，with aramid fibers in the belt ply，the axial stress in the first and second belt ply，circumferential stress in the transverse symmetry plane and terminal circumferential stress of the belt ply decreased，the tire strength and loading capacity were improved.With aramid fibers in the cap ply，the shoulder stress and terminal circumferential stress of cap ply decreased significantly，the uniformity of stress distribution was improved，and the probability of terminal failure of skeleton material was reduced.
