摘　　要：自适应技术被认为是提高传感器飞行器续航能力的有效途径之一,而驱动器是自适应结构可以实施的保障。文中提出了一种"驱动件即结构件"的可伸缩充压管驱动元件,具有驱动和承载双重作用。建立了可伸缩充压管的力学模型并推导得到等效刚度的简化公式。将充压管驱动器应用到某自适应机翼结构中,对机翼在气流扰动下的振动变形进行了仿真。结果表明可伸缩充压管可以产生足够的驱动力和驱动位移,同时可以为自适应结构提供有效的刚度支撑。Adaptive technology is considered as one effective approach to enhance the endurance ability of sensor-craft,and the drivers are the basic system to keep adaptive structures working. In this paper,a kind of pressurized telescopic tube actuator which is capable of both driving and bearing is proposed. The mechanical model of the telescopic tube is established and then its simplified formula of equivalent stiffness is derived. Finally the telescopic tube actuator is applied to an adaptive wing and the vibration deformation of wing under airflow disturbance is simulated. Results show that the pressurized telescopic tube actuator is capable of producing enough driving force and displacement,also providing effective structure stiffness for adaptive structures.
