| 中文摘要: |
| 研究缺气保用轮胎构造（轮廓、支撑胶、三角胶）设计与其性能的相关性。结果表明：方形轮廓对缺气保用轮胎的零气压耐久性能及实车性能均产生不利影响，可以利用有限元方法进行应力分布分析以优化轮廓设计；在满足缺气保用轮胎零气压行驶性能的基础上，尽可能地减小支撑胶厚度，以有利于提升轮胎的整体性能；三角胶应具有足够强度，与支撑胶一起提供失压支撑性能，从而提高缺气保用轮胎的零气压耐久性能。 |
| 英文摘要: |
| The correlation between structure（profile，support compound，apex） design and the performance of the run-flat tire was studied.The results showed that，the square profile had adverse effects on the zero pressure durability and real vehicle performance of the tire，and FEA method could be used to analysis the stress distribution for optimizing the profile design.The thickness of the support compound should be as thin as possible to improve the overall performance of the tire on the basis of meeting the requirements of the zero pressure driving of the tire.The apex should have enough strength to provide the pressure loss in order to support tire performance together with the support compound，so as to improve the zero pressure durability of the tire. |
