| 中文摘要: |
| 在有限元仿真结果与试验结果具有较高相关性的前提下，采用单一变量法，探究轿车子午线轮胎（简称轮胎）的带束层角度与经线密度对其稳态滚动阻力（简称滚动阻力）和侧偏特性的影响。结果表明：与带束层经线密度相比，带束层角度变化更能影响轮胎的动态性能；带束层角度变化对轮胎的侧偏刚性和回正刚性影响较大，对滚动阻力影响较小；轮胎的动态性能随带束层角度与经线密度的变化与轮胎的规格相关。 |
| 英文摘要: |
| Under the premise of high correlation between finite element simulation results and experimental results，the single variable method was used to explore the influence of belt angle and warp density on the steady-state rolling resistance（referred to as rolling resistance） and cornering characteristics of passenger car radial tire（referred to as the tire）.The results showed that compared to the belt warp density，the belt angle variation had a greater impact on the dynamic performance of the tire.The belt angle variation had a significant impact on the cornering stiffness and return stiffness of the tire，but had a smaller impact on the rolling resistance.The above changes in the dynamic performance of the tire were related to its specification. |
