子午线轮胎有着节能、耐用的优点。使用Abaqus有限元软件建立三维有限元轮胎模型并通过将有限元模拟计算结果和实际实验数据对比，验证了模型的正确性。在此基础上，探究了加强层帘线角对胎圈部位应力影响，结果表明：在充气和垂直载荷下，随着帘线角的增加，胎体与加强层端点最大应力、应变能均出现先增后减的趋势。垂直载荷下胎圈部位的刚度随着帘线角增加而一直减小。拟合出了出垂直载荷最大应力、应变能和加强层端点下沉量随帘线角变化的函数。计算得到40.7°的帘线角能够大幅降低加强层端点处的应力、应变能，同时对该处的刚度影响较小。研究结果可为选用适合的加强层帘线角以保证节能和负载的同时减少早期破坏提供理论依据。

TBR tire has the advantages of energy saving and durable. A 3-dimension FEA model about TBR tire was built with Abaqus.The FEA model was provided to be credible by the comparion between the FEA results and the actual test results on real tire. After that, the effect of steel chafer cord angle on TBR tire bead had been studied. The results showed that that the maximum equivalent stress and strain enemy density in the chafer end declined at first and then raised up when chafer chord angle went up.The contrast of vertical stiffness between different angle showed that the vertical stiffnes declined with the rising of cha-fer cord angel. Functions were fit with Cubic Spline Interpolation method to descript these influence. The best angle of maximum equivalent stress and strain enemy density was figure out.The results showed with the angle of 40.7°,the maximum equivalent stress and strain enemy density reduced significantly,and the vertical stiffness depressed little. The results provided theoretical evidence for choose chord the best angle that reducing early failure without declining in energy-saving and loading property .
