| ：通过四因子三水平正交试验，用有限元分析软件Abaqus对235/45R18轮胎带束层帘线截面积、帘线间距、1#带束层帘线角度、2#带束层帘线角度进行优化设计，分析带束层端部的最大Mises应力和最大应变能密度以及胎面最大接地应力。结果表明，带束层帘线截面积为0.16 mm2、帘线间距为1.6 mm、1#带束层帘线角度为58°、2#带束层帘线角度为122°时，轮胎带束层端部的最大Mises应力和最大应变能密度以及胎面最大接地应力最小，轮胎使用寿命更长。 |
| 英文摘要: |
| 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. |
