| Abstract: |
| 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. |
