| 中文摘要: |
| 阐述充气轮胎具有在粗糙路面滚动时能量损失低和垂直刚度、接地压力、承载质量较小的优势以及不抗刺扎、易爆胎、运转不平稳的不足。介绍两款典型的非充气轮胎——辐条式非充气轮胎和蜂巢式非充气轮胎的结构和力学性能。与传统充气轮胎相比，非充气轮胎不仅垂向刚度和接地压力解耦，垂向刚度、侧向刚度、扭转刚度也不再是强耦合关系，这极大地拓展了轮胎的设计空间，仅通过调整剪切带及轮辐的结构和几何参数就可以有效地优化轮胎的性能，但非充气轮胎也存在很多问题，使其仍处于设计研发阶段。今后非充气轮胎的市场需求将不断扩大，其结构和力学性能将不断改进，使非充气轮胎成为轮胎领域的一大品种。 |

| The advantages of pneumatic tires，such as lower energy loss when rolling on rough pavement，and smaller vertical stiffness，contact pressure and load quality，as well as the defects of burst，non-puncture resistance and unstable operation are described.The structure and mechanical properties of two kinds of typical non-pneumatic tires namely，spoke-type non-pneumatic tires and honeycomb-type non-pneumatic tires are introduced.Compared with traditional pneumatic tires，not only the vertical stiffness and contact pressure of non-pneumatic tires can be decoupled，but also the vertical stiffness，lateral stiffness and torsional stiffness are no longer strongly coupled，which greatly expands the variable space in the tire design.And the non-pneumatic tires performance can be effectively optimized only by adjusting the structure and geometric parameters of the shear band and spokes.However，there are many problems with non-pneumatic tires，which are still in the experimental stage.In the future，the market demand of non-pneumatic tires will continue to expand，and its structure and mechanical properties will continue to improve，and these will make non-pneumatic tires a major variety in the field of tire. |
