摘要： 将充有一定压力的轮胎放置于一定臭氧浓度的实验箱环境下，连续转动并施加一定的负荷，模拟在道路上行驶的实际情况下的臭氧加速老化试验。通过设定不同的臭氧浓度臭氧体积分数，施加不同的负荷等条件，观察轮胎表面的龟裂情况，由此来判断轮胎耐臭氧老化的能力。研究了臭氧体积分数、轮胎负荷、轮胎转速3个参数的变化对轮胎龟裂程度的影响，结果表明：臭氧浓度越高，轮胎的臭氧老化龟裂程度越严重，胎肩表现的尤其明显；轮胎施加60%额定负荷时，轮胎的胎肩和胎圈臭氧老化龟裂程度最严重；轮胎转速对轮胎臭氧老化龟裂程度的影响并不显著。

Abstract: The tires with a certain pressure were placed in a laboratory environment with a certain ozone concentration, continuous rotationwith a certain load was applied to simulate the ozone accelerated aging test under the actual conditions of driving on the road. By setting different ozone concentrations, applying different loads and other conditions, we can distinguish the ability of the tires to resist ozone aging through observing the cracks on the surface of the tires after the test. The effects of ozone concentration, tire load and tire speed on the crack rating of the tire were studied.The results showed that the higher the ozone concentration, the more serious the ozone aging cracks of the tire,and the ozone aging cracks of the tire shoulder were particularly obvious.When the 60% rated load was applied, the ozone aging cracks of the tire shoulder andbead were the most serious. The tire speed had no significant effect on the ozone aging cracks of tire.
Key words: tire; dynamic; ozone aging; crack rating
