摘　　要：以刚体系动力学理论为依据,结合飞机起飞着陆运动学特征,建立了起落架-机身组合刚体6自由度全量飞机方程。提出的阶跃跟踪驾驶员时域数学模型,有助于评价起飞着陆阶段人-机系统的飞行品质。然后建立机械操纵系统、电传操纵系统的数学模型,并编制非线性全量时域仿真程序,对起飞着陆动态特性做出了综合的全面的定量分析,其结果与试飞情况吻合。Based on the dynamic theory of rigid body systems and flying characteristics of aircraft during takeoff and landing, a sixdegree freedom aircraft equation of landing gears-aircraft fuselage rigid bodies system is formulated. The time domain step-target tracking pilot model is valuable to the analysis of flying qualities of pilot/vehicle system during takeoff and landing. The mathematical models of mechanical control system and fly-by-wire control system are provided. The nonlinear time domain computer program provides a complete quantitative analysis of aircraft takeoff and landing dynamics, and the numerical simulation results agree well with the real flight test data.
