| 中文摘要: |
| 根据子午线轮胎的特殊结构提出椭圆弧假设，并通过解析法对周向内压应力进行研究，得到子午线轮胎的主要受力部件钢丝带束层的内压应力计算公式，并采用有限元法进行验证。经过本次修正后，子午线轮胎内压应力计算公式可以适应全系列子午线轮胎。 |
| 英文摘要: |
| Based on the special structure of radial tire，an assumption of elliptic arc was proposed，and the circumferential internal stress was investigated by analytic method to obtain an equation for calculating the internal stress of steel belt——the main tension part in radial tire.The equation was verified by FEM.The revised equation for calculating the internal stress of radial tire was applicable to all series of radial tire. |
