| Abstract: |
| The cross-sectional area and spacing of the belt cord，and the angles of 1# and 2# belt cords for 235/45R18 tire were optimized by four-factor and three-level orthogonal test via FEA（finite element analysis） soft Abaqus，and the maximum Mises stress，maximum strain energy density of the belt end and maximum contact stress of the tread were analyzed. The results showed，when the cross-sectional area of the belt cord was 0.16 mm2，the spacing of the belt cords was 1.6 mm，the angle of 1# belt cord was 58° and the angle of 2# belt cord was 122°，the maximum Mises stress and maximum strain energy density of the belt end，and the maximum contact stress of the tread were the smallest，and the service life of the tire was extended. |
