The invention provides a high-frequency micro-vibration isolation device of a spacecraft control moment gyroscope. The high-frequency micro-vibration isolation device is of a central symmetry structure and comprises an installation plate (1), a bottom plate (3) and vibration isolation units arranged between the installation plate (1) and the bottom plate (3). Each vibration isolation unit comprises a radial damping unit (4), an axial damping unit (5) and an elastic supporting unit (6). According to the novel micro-vibration isolation device, vibration isolation performance is good at CMG work rotation speed, six-degree-of-freedom micro vibration transferred to a star body can be effectively reduced, and posture stability and pointing accuracy of the star body can be improved.
Description
technical field [0001] The invention belongs to the technical field of passive vibration isolation, and in particular relates to a high-frequency micro-vibration isolation device for controlling a moment gyroscope of a spacecraft. Background technique [0002] High-performance spacecraft is an important direction of contemporary aerospace development. It is the core equipment for the implementation of accurate target identification and positioning, efficient and safe transmission of space information, deep space exploration and other space missions. Many fields have urgent application requirements and broad application prospects. [0003] A high-performance spacecraft platform needs to have very high pointing accuracy and stability, and a small deviation may have a serious impact on a high-performance spacecraft. For example, for an earth observation satellite at an orbital altitude of 500km, the angular vibration of 2.06arcsec causes the field of view to deviate up to 50m....
