| 中文摘要: |
| 对305/75R24.5无内胎载重子午线轮胎进行结构设计优化，并利用有限元分析软件Abaqus对轮胎充气过程中的外轮廓、负荷下胎圈与轮辋的接触应力、胎肩应力集中和接地压力进行仿真分析评价。有限元分析结果表明，对轮胎外轮廓、胎面花纹和材料分布等结构关键项进行优化设计，可以避免轮胎早期胎肩脱层、胎冠脱层、胎面异常磨损和气密性差等问题。 |
| 英文摘要: |
| The structural design of 305/75R24.5 tubeless truck and bus radial tire was optimized，and the finite element analysis software Abaqus was used to simulate and evaluate the external profile of the tire during the inflating process，the contact stress of tire bead and rim under load，the stress concentration of the tread and the ground pressure.The results of finite element analysis showed that，when the key items such as tire profile，tread pattern and material distribution were optimized，the problems of early tire shoulder separation，crown delamination，abnormal tread wear and poor air tightness were avoided. |
