摘　　要：为自适应调节和改善可展结构动力学性能 ,研制了一种具有传感和作动双重功能的智能主动杆。利用压电材料的正逆压电效应 ,建立了压电微位移作动器的设计模型。给出了智能主动杆的组成和工作原理。研制了一种用于自适应可展结构的新型智能主动杆。该主动杆由压电作动器、微位移传感器、压力传感器等组成 ,具有输出微位移和压力 。A new intelligent member was designed and manufactured which can sense its location and force to adaptively control and improve performance of deployable structures. A design model was developed for a piezoelectric micro-placement actuator based on the actuation effect of piezoelectric materials. The composition of an intelligent active member and its operating mechanism are presented for aerospace adaptive-deployable structures. The new active member includes a piezoelectric actuator, a micro-placement sensor and a pressure sensor to measure the micro-placement and pressure.
