摘　　要：充分考虑飞机地面的受力情况和轮胎的侧偏特性,建立了飞机的平面运动模型,并通过物理方法对飞机的运行状况做了定性分析;基于ADAMS/Aircraft软件建立虚拟样机模型,并对飞机地面操纵和高速滑行时的方向稳定性进行仿真分析;研究结果表明,轮胎的侧偏特性决定了飞机的地面运动轨迹,通过操纵前轮和对称刹车可以使飞机的运行方向趋于稳定。With consideration of the force acting on the aircraft during ground maneuver and the cornering characteristic of the tire, a model of aircraft ground maneuver was established and qualitative analysis was carried on using physical method. The simulating model was based on ADAMS/Aircraft and the analysis was carried on which was about the aircraft ground maneuver and the stability of high speed taxiing. The result showed the ground track depended on the cornering characteristie and aircraft could trend to stable by nose landing gear maneuver and braking symmetrically.
