| 中文摘要: |
| 通过有限元仿真分析研究带束层覆胶模量对工程机械子午线轮胎性能的影响。结果表明：轮胎仿真模型充气后带束层形变以钢丝帘线角度偏转和钢丝帘线间间距变化为主；带束层覆胶模量越大，带束层层间相互作用力传递效率越高，带束层整体刚度越大，轮胎径向刚度越大，胎肩应变能密度集中程度和应变能密度最大值减小，成品轮胎耐久性能明显提升。通过调整带束层覆胶模量改善轮胎耐久性能切实可行。 |
| 英文摘要: |
| The influence of the modulus of the belt layer compound on the properties of the off-the-road（OTR） radial tire was studied by finite element simulation analysis.The results showed that the formation of the belt layer after tire inflation was mainly characterized by angle deflection of steel cords and change in the spacing between steel wire cords.The larger the modulus of the belt layer compound was，the higher the efficiency of the interaction force transmission between the belt layers was，the greater the overall stiffness of the belt layer was，the bigger the radial stiffness of the tire was，decreased the concentration and maximum value of shoulder strain energy density，and the durability of the finished tire had been significantly improved.It was feasible to improve the durability of the tire by adjusting the modulus of the belt layer compound. |
