| 中文摘要: |
| 以10.00R20全钢载重子午线轮胎为例进行钢丝圈钢丝受力分析。利用有限元模型计算得到各种充气压力下钢丝圈钢丝的应力分布特征，并进一步得到钢丝圈钢丝的最大应力和平均应力，它们基本上与充气压力成正比；以最大应力和平均应力分别计算得到的钢丝圈安全系数相差2.3倍。有限元计算结果还表明，超载情况下钢丝圈的安全性能明显下降。 |
| 英文摘要: |
| The stress-strain in the bead wire was analyzed taking 10.00R20 BTR tire as example.A FE model was used to obtain the stress distribution in bead wire of BTR tire under different inflation pressures as well as the maxium stress and the average stress in bead wire. It was found that both the maximum stress and average stress in bead wire were basically proportional to the inflation pressure;the safty factor calculated from the maximum stress was greater than that from the average stress by a factor of 2.3;and the safty of bead wire decreased significantly under overload of tire. |
