| 中文摘要: |
| 以12.00R20全钢载重子午线轮胎原节距花纹为基础，设计出两种新节距花纹。将3种节距花纹以不同的方式进行组合，建立3种变节距花纹轮胎的有限元模型和一个用于结果对比的等节距花纹轮胎的有限元模型。利用Abaqus有限元软件对建立的轮胎有限元模型进行稳态自由滚动工况分析。结果表明，花纹节距对轮胎接地压力和胎体帘线Mises应力有一定的影响，从而为变节距花纹轮胎的设计提供参考。 |
| 英文摘要: |
| In this study，two new pitch patterns were designed based on the original pitch pattern of 12.00R20 truck and bus radial tire.The finite element models of three tires with variable pitch patterns which were generated by combination of two new pitch patterns and the original pitch pattern in three different ways were established，and the finite element model of the tire with regular equal pitch pattern was also established for comparison.The four finite element models were analyzed under the free rolling condition of tire by using Abaqus software.The results showed that the tire tread pattern pitch had impact on the contact pressure and the Mises stress，and it provided a useful reference for design of tire tread pattern pitch. |
