| Abstract: |
| By using the finite element analysis software Abaqus，3-D finite element model of the nonpneumatic tire was established by taking 2.50－14 non-pneumatic tire with type C hole as the research object. Targeting the optimization of the maximum stress of supporting structure and grounding area of the non pneumatic tire，the orthogonal test was carried out to analyze four factors：the radius of the hole arc，the number of the supporting structure，the width of the hard elastomer layer and the thickness of the hard elastomer layer.The results showed that the supporting structure performance，load-carrying capacity and grounding performance of the non-pneumatic tire were greatly improved with the optimal design in which the inner radius and outer radius of the hole arc were 17 mm and 20 mm，respectively，the number of the supporting structures was 40，the width of the hard elastomer layer was 44 mm，and the thickness of the hard elastomer
layer was 6 mm. |
