中文摘要: |
研究轮胎动态和静态臭氧老化现象。结果表明:动态臭氧老化试验中,轮胎受变应力作用会有较大的应变,应力集中在胎圈和胎肩位置,导致裂纹趋向于更加密集、细小;静态臭氧老化试验中,轮胎在充气状态下受恒定应力作用,受力均匀,裂纹趋向于稀疏、粗大;臭氧浓度越大,轮胎龟裂程度越明显;动态和静态耐臭氧老化产生的裂纹均为水平方向。 |
英文摘要: |
The dynamic and static ozone aging of tires was studied.The results showed that,in dynamic ozone aging test,the tire would have larger strain under the action of variable stress,and the stress of tire was concentrated in the position of bead and shoulder,which leaded to more dense and fine cracks.In static ozone aging test,the tire was under constant stress under inflation condition,and the stress was uniform,and the crack tended to be sparse and thick.The higher the ozone concentration,the more obvious the crack degree of the tire.The cracks produced by dynamic and static ozone aging were horizontal. |
