| 中文摘要: |
| 通过轮胎胎圈压力试验机模拟分析胎圈结构设计的合理性，节省试验时间和成本。在了解此试验机原理的基础上，通过有限元仿真的方法计算得到与试验结果相同或者近似的胎圈压力曲线。通过对185/65R15规格半钢子午线轮胎一系列的方案设计以及仿真分析，找到了正确进行胎圈压力仿真的方法，误差达到25%以下；考虑到制造过程存在波动，这一误差在可接受范围之内，证明仿真方法切实可行，能够很好地模拟胎圈压力试验。 |

| The quality of bead rim design was analyzed by using bead compression testing in order to reduce experiment time and cost.The finite element （FE） simulation method was then applied to simulate the relationship curves between the bead compression force and rim expansion distance which were the same as or close to the experimental testing results.The optimized FE simulation method with acceptable error below 25% was obtained by analysis of simulation designs and the results of the bead compression characteristics using 185/65R15 tire as an example.It was well demonstrated that FE modeling of bead compression was effective and the predicted bead compression force was acceptable. |
