Aircraft tire suffers from high-speed friction due to harsh conditions in landing, which leads to high temperature and the short service life. So, the effect of different sliding speeds on the tribology behaviors of tread rubber was studied theoretically and experimentally. Firstly, high-speed friction and wear tests were carried out by using a self-developed high-speed friction testing apparatus. Then, a thermo-mechanical coupling model was developed to predict the friction temperature of rubber specimen by ABAQUS software. Finally, tribology behaviors of friction temperature, coefficient of friction (COF) and wear performance have been revealed. Results indicated that temperature and wear loss increased when sliding speed increased; however, COF decreased with increasement of sliding speed; ploughing was the main mechanism in rubber abrasion, and thermo-chemical degradation appeared at wear track; the predicted temperature rise was in good agreement with the experimental results.

飞机轮胎在着陆时因条件恶劣而受到高速摩擦，导致温度高，使用寿命短。因此，从理论上和实验上研究了不同滑动速度对胎面橡胶摩擦学行为的影响。首先，利用自主研发的高速摩擦试验装置进行了高速摩擦磨损试验。然后，利用ABAQUS软件建立了一个热力耦合模型来预测橡胶试件的摩擦温度。最后，揭示了摩擦温度、摩擦系数 (COF) 和磨损性能的摩擦学行为。结果表明，随着滑动速度的增加，温度和磨损损失增加；但随着滑动速度的增加，COF 下降；耕作是橡胶磨损的主要机制，磨损轨迹出现热化学降解；预测的温升与实验结果非常吻合。
