| 中文摘要: |
| 针对12.00R20全钢载重子午线轮胎，基于组合模型技术建立带复杂花纹的全局模型，基于子模型技术建立胎冠部位具有精细网格的接地区子模型，并验证其有效性。应用子模型精确模拟静负荷工况下胎冠部位橡胶结构的应力应变特征，并分析胎冠部位5个危险区域的应力情况。结果表明，子午线轮胎的带束层端部（区域M）在使用中是最容易破坏的位置，由于材料及结构均存在突变，其应力集中和剪切变形在整个胎冠部位是最严重的。基于本研究结果，提出了改进方法。 |

| For 12.00R20 truck radial tire，the global model with complex pattern based on combined model technology and the submodel with fine grid in the crown based on submodel technique were established and verified.The stress and strain characteristics of the rubber structure in the tire crown under static load condition were simulated accurately by using submodel，and the stress of five weak areas in the crown was analyzed.The results showed that，the end of the belt (area M) was most vulnerable to be damaged，and because of the transition of material and structure，its stress concentration and the shear deformation were most serious in the whole crown area.Then the improved method was put forward based on the simulated results. |
