| 中文摘要: |
| 采用有限元模拟方法对全钢巨型工程机械子午线轮胎胎圈的受力情况进行分析，包括胎圈 轮辋配合紧密度、钢丝圈安全性、充气后胎圈轮辋接触情况、胎圈轮辋法向应力分布、胎圈Von Mises应力分布、负荷下轮胎轮辋接触情况，并进行胎圈优化设计，使胎圈受力状况合理，胎圈过盈配合恰当，并保证轮胎的气密性。 |
| 英文摘要: |
| In this paper,the pressure distribution of the bead in giant all-steel off-the-road radial tire was analyzed by using finite element analysis method.This study included the closeness between bead and rim,safety of bead ring,contact between bead and rim after inflation,normal pressure on bead and rim,Von Mises stress distribution on bead,and contact between bead and rim under load.The design of bead was optimized.As a result,the pressure distribution was optimized,the interference fit of the bead and the rim was better,and the air tightness of the tire was good. |
