| 中文摘要: |
| 以235/45R18子午线轮胎为基础，以质量小、弹性优异的发泡弹性聚氨酯（E-TPU）为内支撑体制备新型安全轮胎，用非线性有限元软件ABAQUS对其进行静态力学特性分析。结果表明：新型安全轮胎采用连通充气设计，能够在标准气压下正常行驶，不影响其操控性和舒适性；当轮胎漏气时，内支撑体与轮胎内衬层接触，内支撑体与胎侧共同承受载荷，从而减小胎侧部位的形变量，保证车辆能正常行驶到安全区域。 |
| 英文摘要: |
| New type safety tire with foaming elastic polyurethane（E-TPU） inner support body with samll mass and excellent elastic resilience was designed based on 235/45R18 radial tire.Then the static mechanical properties were analyzed by nonlinear finite element software ABAQUS.The results showed that，this new type safety tire was designed with connected inflatable structure，which can drive normally under standard air pressure and its handling and comfort were not affected.When the air pressure of tire was lower than the standard air pressure，the inner support body contacted with tire inner liner.The inner support body and the sidewall bore the load together.Thus，the shape variable of the sidewall could be reduced，and ensured the normal driving of the vehicles to the safe area. |
