| 摘 要： | 研究弹性飞行器的动态耦合问题，首先导出了非定常气动力作用下的弹性飞行器的纵向运动方程。就简化的非定常气动力数学模型提出了分析气动弹性飞行器稳定性的影响方法，而后对弹性飞行器的动态耦合特性提出了定性的分析方法。并从有效抑制飞行器的弹性振动角度，研究了主动反馈控制、操纵面及陀螺位置的合适选择的协同设计问题。

| Abstract: | Dynamic stability and coupling problem of elastic vehicles is studied in this paper. Firstly, longitudinal equations of disturbance motions are derived. With simplified unsteady aerodynamic force mathematical model, method of analysis for the effects of aeroelasticity on the dynamic stability of elastic vehicles is established. Then method of qualitative analysis of dynamic coupling of elastic vehicles is proposed, and proper design of active feedback control choose of positions of control surface and gyro are studied from the point of view for efficient suppression of elastic vibrations of flight vehicles. |
