| 中文摘要: |
| 基于Abaqus软件组合模型技术建立了带复杂花纹的子午线轮胎全局模型，同时基于子模型技术建立了带束层的精细网格有限元分析子模型。分析对比结果表明：子模型能更准确地反映带束层的受力特征；在充气工况下，胎冠中部带束层应力远大于边缘部位，各截面内骨架结构受力分布关于轮胎中分面基本对称；在静负荷工况下，接地区胎冠部位帘线受力相对充气工况有所减小，胎侧帘线受力有所增大，帘线受力分布呈现出严重的不对称性。 |
| 英文摘要: |
| A global finite element model of radial tire with complex pattern was established using Abaqus software,and a fine grid finite element submodel of the belt was established based on sub-model technology.Analysis and comparison results showed that, submodel could describe the force characteristics of the belt more accurately.Under inflated condition, the stress of crown central belt was much larger than that around edges,and the force distribution on the reinforcing materials was symmetrical.Under static load condition,the crown cord force in contact area was reduced compared with inflated condition,the sidewall cord force was increased,and the cord force distribution was ra-ther asymmetrical. |
