| 中文摘要: |
| 采用有限元方法分析全钢载重子午线轮胎胎脚裂的原因，并提出相应解决措施。造成全钢载重子午线轮胎胎脚裂问题的主要原因是胎脚底面的较大摩擦功发生在接触压力较大、横向剪力交变处附近，致使该位置发生过度磨损。采取胎体反包和胎圈包布外侧高度均降低10 mm、增加2层锦纶加强层及增大钢丝圈直径等优化措施，可降低胎脚底面与轮辋内表面间的摩擦功，减缓或避免该问题的发生。 |
| 英文摘要: |
| The foot crack of truck and bus radial (TBR) tire was analyzed by finite element method，and the corrective actions were put forward. The main reason of foot crack in TBR tire was the high friction of foot bottom surface near the place with large contact pressure and transverse shear transition， which resulted in excessive wear in that position. The corrective actions were reducing turnup height of carcass ply and outer height of chafer by 10 mm， respectively， adding 2 nylon reinforcement layers， and increasing the diameter of bead. After the modification， the friction between the foot bottom surface and rim inner surface was reduced， which could slow down or avoid the occurrence of foot crack. |
