| Abstract: |
| The non-pneumatic tires do not have the risk of burst，and the fatigue performance is a key
performance indicator during their design process. Based on the fatigue crack propagation theory of rubber
materials and the critical plane analysis method，the fatigue life prediction of the elastic spoke of the nonpneumatic
tire was carried out using the finite element analysis method of the joint simulation of Abaqus and
Endurica software. The influence of finite element mesh type and mesh size on the fatigue life of the elastic
spoke of the non-pneumatic tire was systematically analyzed，providing theoretical and technical supports for
the optimization design of high-performance and long-life non-pneumatic tires. |
