| 中文摘要: |
| 在振动试验机上测试轿车子午线轮胎的静态径向刚度。研究气压和结构参数（带束层宽度、0°冠带层层数和胎面胶厚度）对轿车子午线轮胎静态径向刚度的影响。结果表明，轮胎的径向刚度随气压的升高而增大，轮胎结构的变化对径向刚度影响不大。 |
| 英文摘要: |
| The static radial stiffness of PCR tire was measured with a vibration tester.The effect of the inflation pressure and the construction parameters (belt width，crown ply number and tread gauge) on the static radial stiffness was investigated.The results showed that the static radial stiffness increased with the inflation pressure，and the changes of the studied tire construction parameters had little effect on the static radial stiffness. |
