Based on the characteristics of kangaroo’s lower limb structure, a 195/50R16 flexible spoke bionic non-pneumatic tire model is established through the methodology of non-pneumatic tire unit configuration. From the radial stiffness coupling model, and based on numerical and theoretical derivation, the accuracy of the radial stiffness coupling model is confirmed. By comparing a pneumatic tire with the same size, a radial stiffness comparison experiment is carried out to ensure the accuracy of numerical analysis. The radial stiffness, lateral stiffness, longitudinal stiffness, torsional stiffness, and ground pressure of the tires under different loads are studied. The results show that the flexible spoke bionic non-pneumatic tire has better performance than the pneumatic tire. This study guides the industrial production of flexible spoke bionic non-pneumatic tires. At the same time, it also provides a new idea of theory and methodology for the research of non-pneumatic tires.

根据袋鼠下肢结构的特点，通过非充气轮胎单元配置方法建立了195 / 50R16柔性辐条仿生非充气轮胎模型。从径向刚度耦合模型，并基于数值和理论推导，确定了径向刚度耦合模型的准确性。通过比较相同尺寸的充气轮胎，进行了径向刚度比较实验，以确保数值分析的准确性。研究了轮胎在不同载荷下的径向刚度，横向刚度，纵向刚度，扭转刚度和地面压力。结果表明，柔性辐条仿生非充气轮胎具有比充气轮胎更好的性能。这项研究指导了柔性辐条仿生非充气轮胎的工业生产。同时，也为非充气轮胎的研究提供了理论和方法论的新思路。
