| 中文摘要: |
| 设计一种以弧形等厚板簧为主要承载部件的新型非充气轮胎，建立其有限元模型，仿真模拟静态径向加载与稳态纯滚动工况，得出轮胎径向刚度和径向力，对接地压力参数进行评价，计算出轮胎有效滚动半径。结果表明：在静态径向加载条件下，轮胎径向力与径向位移近似线性正相关，径向刚度和径向力随板簧厚度增大而增大；轮胎接地印痕中心出现应力集中现象，板簧越厚则平均接地压力越大，胎面不均匀磨损程度越高；轮胎有效滚动半径随径向载荷增大线性减小。本研究可为非充气轮胎性能分析或者结构优化提供参考。 |

| A new type of non-pneumatic tire was designed，which takes the arc-shaped equal thickness leaf spring as the main load bearing component.The finite element model was established to simulate the static radial loading and steady-state pure rolling conditions，the radial stiffness and radial force of the tire were obtained，the parameters of the tire contact pressure were evaluated，and the effective rolling radius of the tire was calculated.The results showed that under the static radial loading condition，the radial force and radial displacement of tire were approximately linear positive correlation，and the radial stiffness and radial force increased with the increase of leaf spring thickness.The stress concentration occured in the center of the tire contact area.The thicker the leaf spring was，the greater the average pressure of the tire was and the higher the uneven wear degree of the tread was.The effective rolling radius of the tire decreased linearly with the increase of radial load.The research results could provide reference for performance analysis or structural optimization. |
