| Popis: | This study focuses on the basic characteristics of a variable-damping isolator using a bio-metal fiber (BMF) valve to enhance the pointing performance of optical equipment on-board satellites. A variable-damping BMF valve isolator for isolating disturbances induced by reaction-wheel operation has been designed and fabricated. The opening and closing of the valve to change the damping of the isolator is implemented by using characteristic variation of the bio-metal fiber to the input electric current. The BMF isolator fabricated in this study has the advantages of being a simple variable-damping device with low power consumption, unlike conventional variable-damping devices, such as solenoid-valve-type oil dampers and ER or MR dampers. This paper presents the basic characteristics of the BMF isolator obtained from dynamic tests of the isolator. |
