Other Abstract

For a kind of flexible hinge with adjustable spring stiffness,which is used to connect small spacecraft and solar panels,the influence of damping on the vibration response of flexible hinge plate system in hinge structure is studied,including hinge stiffness and friction of hinge rotating pair. Firstly,a piezoelectric flexible hinged flexible plate experimental platform is established. The piezoelectric sensor and laser displacement sensor are used to detect vibrations,and a piezoelectric actuator is used for persistently exciting vibration. Then,experiments are carried out on vibration modal analyses under external excitation and driven via the piezoelectric actuator,under the conditions of different torsional stiffness of the flexible hinge. The experimental results show that the stiffness and the friction damping factor of the rotating pair of the flexible hinge will affect the natural frequency and damping ratio of the fundamental frequency vibration of the flexible hinged plate system. The experimental results provide a reference for analyzing the hinge influence characteristics of flexible hinged plates.
