摘要

作为分离火箭向卫星传递振动的有效手段，全星隔振技术在近20年来得到了广泛的研究和应用。基于一种新型圆形载荷适配器(CPAF)，研究了CPAF的振动原理，建立了相应的隔振模型。在被动振动控制的基础上，利用压电叠层作动器实现了被动和主动振动的集成控制。模型仿真结果表明，CPAF具有良好的隔振性能，可以在较宽的频带内减小火箭向卫星传递的振动。

Vibration control of flexible satellites using a new isolator

As an effective means of separating the vibration transmitted from rocket to satellite, the Whole-Spacecraft Vibration Isolation (WSVI) has been widely studied and applied in the past 20 years. Based on a new Circular Payload Adapter Fitting (CPAF), this paper studied the vibration principles of the CPAF and established corresponding vibration isolation model. With the piezoelectric stack actuators, integrated passive and active vibration control was achieved based on passive vibration control. Model simulation results show that the CPAF has good vibration isolation performance, and could reduce the vibration transmitted from rocket to satellite in a wide frequency band.
