The optical payload passive vibration isolation system solves the problem that existing vibration isolation platforms are prone to damage when the satellite's ascent acceleration is too large, and belongs to the field of spacecraft micro-vibration control technology. The configuration of the system of the present invention is that three upper mounting supports are distributed and fixed on the side of the upper platform. The mounting base of the eddy current damper is fixed on the lower platform, and the six legs are divided into three groups, and the tops of the two legs of one group are fixed on the same upper mounting base, and an eddy current damper is installed at the bottom of each leg And the eddy current damper is fixed in the eddy current damper mounting seat on the lower platform; the plane of two outriggers of one group is perpendicular to the plane of the upper platform and the plane of the lower platform at the same time, and the eddy current damper at the bottom of the three sets of legs The mounting seats are distributed on three sides of the equilateral triangle, and the mounting seats of the eddy current damper at the bottom of a group of legs are located on one side.
Description
technical field [0001] The invention relates to a vibration isolation system, in particular to a passive vibration isolation system for an optical payload, and belongs to the technical field of spacecraft micro-vibration control. Background technique [0002] During the in-orbit operation of the spacecraft, the rotation of the rotating parts on the spacecraft, the stepping motion of the drive mechanism, the operation of the thruster, the mechanical movement of the compressor and other components, the vibration of the large flexible structure itself, and the thermal deformation induced when entering and leaving the shadow area, etc. Both will cause the spacecraft to produce a vibration response with a small vibration amplitude and a wide frequency range, that is, micro vibration. The problem of microvibration widely exists in various spacecraft, but because of its small vibration amplitude, it has little impact on most space activities, and most of them are not considered.
