| 中文摘要: |
| 在下沉量和接地印痕有限元仿真结果与试验结果具有高相关性的前提下，采用单一变量法，探究轿车子午线轮胎（简称轮胎）带束层角度与经线密度变化对其下沉量、接地印痕、径向刚性及横向刚性类静态性能的影响。结果表明：与带束层经线密度相比，带束层角度变化对轮胎的下沉量、接地印痕和刚性影响较大；轮胎的径向刚性和横向刚性随带束层角度的增大呈减小趋势；轮胎的静态性能随带束层角度变化的趋势还受轮胎的扁平率影响。 |
| 英文摘要: |
| Under the premise of a high correlation between the finite element simulation results and the experimental results of the deflection and footprint，the single variable method was used to explore the effects of belt angle and warp density variation of passenger car radial tire（referred to as the tire） on its static performance such as the deflection，footprint，radial stiffness and lateral stiffness.The results showed that compared to the belt warp density，the belt angle variation had a greater impact on the deflection，footprint and stiffness of the tire.The radial stiffness and lateral stiffness of the tire decreased with the increase of the belt angle.The trend of the static performance of the tire with the belt angle was also influenced by the flatness of the tire. |
