Abstract
A low-power-consumption magneto-rheological (MR) fluid damper has been designed andfabricated to suppress the vibration of a space flexible structure. The MR damperfabricated in this study has advantages of both semi-active and optimal passive dampers,unlike the conventional MR and electro-rheological (ER) fluid semi-active damper. Thevibration is thus damped quickly when the damper is controlled semi-actively, and thevibration energy is dissipated by an optimal passive damper in the absence of control. Toimplement the aforementioned damper, we fabricated an electromagnet combined with apermanent magnet. Its performance and the characteristics of the damper with the newlydeveloped electromagnet were subsequently measured. The performance of thedamper has been confirmed by vibration suppression experiments using 10-bay trussstructures.
