摘　　要：对现代飞机操纵面操纵系统刚度进行了分析,从满足气动弹性需求的角度给出了作动器动刚度和阻尼要求的确定方法。以某支线飞机升降舵操纵系统为例,给出了操纵系统刚度和阻尼要求;针对方向舵操纵面旋转频率过低问题,提出了方向舵作动器布置下移与实肋对接的更改建议。经分析,更改后的方向舵作动器布置能够满足气动弹性设计要求。The control system stiffness of modern airplane was analyzed. The actuator dynamic stiffness and damping requirement of control surface were proposed according to the aeroelasticity requirement. Taking the elevator of the regional airplane as an example, giving stiffness and damping requirement of the control system, and put forward a suggestion to move the actuator down and make it join the real rib for solving the issue of too low rotation frequency of rudder. The improved rudder layout scheme could meet the aeroelasticity requirement.
