| 中文摘要: |
| 采用有限元分析方法研究全钢载重子午线轮胎胎圈部位采用锦纶包布层以及锦纶包布帘线与胎体帘线成不同角度情况下的胎圈性能。结果表明，当锦纶包布帘线与胎体帘线的夹角较小时，胎体反包端点上单元和右单元的综合应变和综合应力较小，胎体反包端点的剪应变和应变能密度也较小；夹角增大及无锦纶包布时，综合应变、综合应力、剪应变和应变能密度增大，说明采用锦纶包布、减小锦纶包布帘线与胎体帘线的夹角有利于提高胎圈性能。 |
| 英文摘要: |
| The influence of the nylon flipper and the angle between nylon flipper cord and carcass ply cord on the performance of bead in TBR tire was investigated with FEA.The results showed that the comprehensive stress and strain at the upper unit and right unit of carcass ply turn-up point as well as the shearing strain and the strain energy density at the carcass ply turn-up point were less as the angle between nylon flipper cord and carcass ply cord reduced;the comprehensive stress and strain as well as the shearing strain and the strain energy density increased as the nylon flipper cord eliminated or the angle between nylon flipper cord and carcass ply cord reduced.It was concluded that the application of the nylon flipper and the less angle between nylon flipper cord and carcass ply cord was beneficial to improve the performance of tire bead. |
