摘　　要：通过对侧风作用下的飞机受力进行分析,建立了轮胎-道面相互作用理论模型,得到了侧风作用下两者相互作用的主要影响因素,并进一步基于有限元分析软件ABAQUS建立了侧偏轮胎-道面有限元模型,研究了轮胎不同侧偏角度以及跑道不同积水厚度等因素对于飞机轮胎与道面相互作用的影响规律变化情况。研究结果表明:飞机在跑道滑行时在侧风作用会产生偏离跑道中心线的趋势,道面对轮胎的侧偏力是影响飞机质心偏离跑道中心线距离的重要因素;轮胎侧偏角增大导致轮胎接地非对称性增强,轮胎迎水面的区域长度也呈逐步增大趋势;轮胎迎水面的动水压强呈非对称分布,动水压强较高的区域出现在轮胎的偏转侧,并且最大值接近于1 MPa,此时易出现滑水风险;而随着跑道道面水膜厚度的逐渐增加,道面相应的侧向摩擦因数也在减小,当水膜厚度达到机场运行管理规定中临界值13 mm时,道面摩擦因数仅为干道面时的一半,大大增加飞机偏出跑道风险。By analysing the aircraft forces under the effect of crosswind,the theoretical model of tire-pavement interaction is introduced to obtain the main influencing factors in crosswind and ABAQUS is used to establish the interaction model between the cornering tire and the runway pavement.The effect of the slip angle and different runway water thicknesses on the interaction between aircraft tires and the pavement surface is studied.The results indicate that the crosswind causes the aircraft to deviate from the runway center line when the aircraft taxis,and the slide force of the tire on the runway pavement is an important factor affecting the distance of the aircraft’s center of mass from the runway center line.An increase in tire slip angle leads to an increase in tire grounding characteristics and a progressive increase in the length of water front area.The distribution of water front pressure increases asymmetrically,in which the high pressure area is concentrated on the side of tire deflection and the maximum value is close to 1 MPa.At this time,there is a risk of water skiing.With the increase of the thickness of water,the lateral friction coefficient of the wet pavement decreases.When the thickness of water reaches the critical value of 13 mm in the airport operational regulations,the lateral friction coefficient of the wet pavement is only half of that of the dry pavement,which greatly increases the risk of aircraft deviating from the runway.
