Abstract

For aim of providing a stable working environment for those sensitive payloads on-orbit, typically the space telescope and laser communication equipment and so on, micro-vibrations generated by those instruments should be taken measures to suppress. Therefore, this article proposes a novel vibration isolation stage for controlling the low frequency vibration caused by solar arrays, which is difficult to suppress by traditional methods. By adoption of compliant mechanism embedded multilevel amplifiers and giant magnetostrictive actuator, not only the large working stroke with nano-precision could be achieved, but also the required stable output capability in low frequency is obtained. The conceptual scheme and working principle are presented firstly in this paper. And then the theoretical amplification ratio model is constructed and static analysis and dynamic analysis are carried out by ANSYS. Finally, experimental tests are conducted for verifying the related performance. It proves that the proposed stage is capable of suppressing low frequency disturbance.
