| 中文摘要: |
| 采用有限元分析方法对全钢载重子午线轮胎六角形钢丝圈与圆形钢丝圈进行结构和性能对比分析。结果表明，圆形钢丝圈及其底部胶料在轮胎中受力和非受力状态下的应力变化率小于六角形钢丝圈，其在受力作用时的变形量也较小，更有利于将轮胎束紧在轮辋上，可有效预防胎体钢丝断爆现象。 |
| 英文摘要: |
| The structure and property of hexagonal bead and round bead for truck and bus radial tire were compared using finite element analysis method.The results showed that， the rate of stress change of round bead and its bottom compound in tires under either load or unload situation was smaller than that of the hexagonal bead，and its deformation under load was lower，which was helpful to tighten the tire on the rim，and would effectively improve the burst resistance of carcass wire. |
