摘　　要：以新开发的175/70R14半钢子午线轮胎为研究对象,针对胎体帘布反包端点裂口问题建立有限元仿真模型。根据有限元分析结果提出增大胎体帘布反包端点高度的改进措施。结果表明,增大胎体帘布反包高度能够有效改善胎圈裂口现象,提高胎圈耐久性能;有限元分析结果与试验结果有很好的一致性。Taking the newly developed 175/70R14 steel-belted radial tire as the research object,a finite element simulation model was established to solve the problem of the turn-up end-point crack of carcass cord.According to the results of finite element analysis,improvement measures were put forward.The results showed that increasing the turn-up height of carcass cord could solve the problem of bead cracking,and improve the bead durability.The finite element analysis results were in good agreement with the test results.
