| Abstract: |
| A staggered structure non-pneumatic safety tire was proposed，and its static grounding performance was analyzed by finite element analysis software Abaqus.The stress（S）-fatigue life（N）curve of polyurethane support material of the tire was measured by Demencia fatigue test and imported to fatigue analysis software FE-SAFE to predict the fatigue life of the tire.The results showed that，the static stiffness curve of the tire was consistent with the same size pneumatic radial tire，the contact area and average contact pressure was similiar，which indicated that the tire had reached the service performance of the same size pneumatic radial tire，and the fatigue life was similiar. |
