| 中文摘要: |
| 采用数值仿真分析技术对13.00R25工程机械子午线轮胎进行了结构设计优化，重点研究胎圈、胎侧部位加强层插入包对轮胎承载性能的影响。结果表明：3种方案轮胎充气后的外直径和断面宽增幅相差不大，其中方案3增幅最大；在充气压力为950 kPa、加载负荷为8 500 kg时，3种方案轮胎的接地印痕相差不大，但方案2胎面冠部到胎肩所受的应力较为均匀，其对应的垂直载荷最大。在胎侧部位增设锦纶加强层插入包，可使轮胎胎面冠部受力更加均匀，提高轮胎的耐磨性能，同时增大了胎侧部位刚性，延长了轮胎的使用寿命。 |
| 英文摘要: |
| The structure of 13.00R25 off-the-road radial tire was modified by using numerical simulation analysis technology，and the influence of bead and sidewall reinforcement package on the loading performance of tire were investigated.The results showed that，the increase amplitude of inflated overall diameter and cross sectional width of the tires in all three designs were similar，though the 3rd design showed slightly higher increase.As the inflation pressure was 950 kPa and the loading was 8 500 kg，the footprint of the tires were similar，but the stress from crown to shoulder of the tire from 2nd design was more uniform，and its vertical loading was the biggest.When nylon reinforcement package was added in the sidewall，the stress of crown could be more uniform，the wear resistance was improved，the rigidity of sidewall increased，and the service life of tire prolonged. |
