摘　　要：湿滑道面会造成飞机制动性能下降,影响起降安全。通过搭建污染跑道摩擦特性测试装置,根据飞机在湿滑道面滑跑的实际情况,对飞机轮胎在不同水膜厚度、速度、载荷条件下运行的接触力、滑移距离进行研究,分析了湿滑条件下道面摩擦特性与影响因素间的关系。实验结果表明:水膜厚度对道面摩擦特性影响显著,水膜厚度为13 mm时,轮胎与道面之间的接触应力变化明显,滑移距离大幅度增加。随着速度的增加,轮胎与道面之间的接触应力呈线性增加趋势,过高的速度会增加滑水风险。轮胎载荷的增加会减少湿滑道面上的滑移距离,在一定程度上提高飞机轮胎的载荷,能有效改善湿滑道面上的摩擦特性。Wet runway surface will cause aircraft braking performance degradation and affect takeoff and landing safety.The contact force and slip distance of aircraft tires running under different water film thickness,speed and load conditions were studied according to the actual situation of aircraft running on wet slippery surfaces by building a test device for the friction characteristics of contaminated runways,and the relationship between the friction characteristics of tire surfaces and the influencing factors under wet slippery conditions was analyzed.The experimental results show that the water film thickness has a significant impact on the pavement friction characteristics.When the water film thickness is 13 mm,the contact stress between the tire and the pavement changes significantly,and the slip distance increases significantly.With the increase of speed,the contact stress between tire and pavement increases linearly,and too high speed will increase the risk of water skiing.The increase of tire load will reduce the slip distance on the wet skid surface,increase the load of aircraft tires to a certain extent,and effectively improve the friction characteristics on the wet skid surface.
