中文摘要:
      提出一种新型子午斜交轮胎结构，即将子午线轮胎胎侧部位的胎体帘线子午结构改为斜交结构，并利用有限元模型对子午斜交轮胎和子午线轮胎的特性进行对比分析。结果表明：与子午线轮胎相比，子午斜交轮胎的径向刚度较高；胎侧应变能密度分布较连续且相对均匀，且最大应变能较低；胎面横向接地压力分布较均匀、尤其是胎肩处的应力集中区域较小，接地印痕形状近似椭圆形；带束层边缘的剪切应变峰值较小。
英文摘要:
      A new radial-bias tire structure was proposed，in which the radial structure of carcass cords in the sidewall was changed to bias structure.The characteristics of radial-bias tire and radial tire were analyzed by using finite element model.The results showed that，compared with radial tire，the radial stiffness of radial-bias tire was higher；the strain energy density distribution in sidewall was continuous and relatively uniform，and the maximum strain energy was lower；the lateral ground pressure distribution of tread was more uniform，especially the stress concentration area at the shoulder was smaller，and the footprint was approximately elliptical；the peak value of shear strain at belt edge was smaller.
