| 中文摘要: |
| 对比研究1670dtex/1芳纶和1400dtex/1锦纶66混纺冠带材料与1400dtex/1锦纶66冠带材料对轮胎性能和整车主观测试性能的影响。结果表明：与1400dtex/1锦纶66冠带材料轮胎相比，混纺冠带材料轮胎的充气外直径减小，充气断面宽增大；接地压力分布更均匀；静态刚性中横向刚性较小，径向刚性相当，纵向和扭转刚性较大；滚动阻力增大；整车主观测试中，操纵稳定性和转向性能提高，舒适性能下降，与轮胎六分力的相关测试数据吻合。 |
| 英文摘要: |
| The effect of 1670dtex/1 aramid and 1400dtex/1 nylon 66 blended cap-ply materials and 1400dtex/1 nylon 66 cap-ply materials on tire performance and vehicle subjective testing performance was comparative studied.The results showed that compared with 1400dtex/1 nylon 66 cap-ply material tires，the inflated outer diameter of blended cap-ply material tires decreased，the inflated cross-sectional width increased，and the distribution of grounding pressure was more uniform.In static rigidity，the lateral rigidity was relatively small，the radial rigidity was equivalent，and the longitudinal rigidity and torsional rigidity were relatively large，and the rolling resistance increased.In the vehicle subjective testing，the handling stability and steering performance were improved，while the comfortability decreased，which was consistent with the relevant test data of six component force of the tire. |
