| 中文摘要: |
| 介绍在进行轮胎有限元结构分析时建立正确的力学模型应注意的问题：对于轮胎中的橡胶材料和橡胶-帘线复合材料，要准确描述和正确输入其材料特性；对于轮胎存在的大变形和接触问题，需采用合理的单元进行模拟；为预测轮胎的局部力学行为，应采用三维实体单元模拟，并在接地区附近采用细化网格。 |
| 英文摘要: |
| To obtain a correct FEA model of tire structure，attention should be paid to the following problems：exactly describe and correctly input the material characteristics of rubber or rubber/cord composite；simulate the large deformation and contact area of tire with reasonable units；use 3D solid unit model and fine network near ground-contact area to predict the local mechanical behaviour of tire. |
