| 中文摘要: |
| 针对235/60R16半钢子午线轮胎出现的胎侧周向凹痕问题，利用有限元分析方法对轮胎进行充气模拟及凹痕产生机理分析，研究充气压力、胎体帘线材料和结构参数对凹痕的影响。结果表明：胎侧周向凹痕与轮胎充气状态有关，凹痕不会引起塑性形变，充气压力越大，凹痕越明显；凹痕产生的主要原因是胎体反包端点附近受较大的拉伸应力作用，通过适当降低胎体反包高度、减小胎体帘布层宽度，解决了胎侧周向凹痕问题。 |
| 英文摘要: |
| Aiming at the problem of sidewall circumferential dent of 235/60R16 steel-belted radial tire，the inflation simulation and dent generation mechanism analysis of tire were carried out by using finite element analysis method，and the effects of inflation pressure，carcass cord material and structure parameters on dent were studied.The results showed that the sidewall circumferential dent was related to the inflation state of the tire，and the dent would not cause plastic deformation.The higher the inflation pressure was，the more obvious the dent was.The main reason for the dent was that there was a large tensile stress near the turn-up end of the carcass.The sidewall circumferential dent problem was solved by appropriately reducing the turn-up height and the cord width of the carcass. |
