Abstract

The invention discloses a space six-degree-of-freedom magnetic suspension vibration isolation platform, which belongs to the technical field of space payload vibration isolation. The invention solves the problems that the existing magnetic levitation platform occupies a large space, has a complicated structure and low degree of integration. The four coil arrays are correspondingly located between the four upper permanent magnet arrays and the four lower permanent magnet arrays, and the connecting cylinder is set in the enclosed area of ​​the four coil arrays. Each permanent magnet array includes permanent magnets and magnetic poles with a horizontal magnetic pole direction. Permanent magnets with a vertical direction, when working, the coil array receives the Lorentz force in the horizontal and vertical directions in the magnetic field generated by the upper permanent magnet array and the lower permanent magnet array, and realizes horizontal and vertical movement control. Using electromagnetic drive, six degrees of freedom can be realized. The mechanism responds quickly, easy to realize high-precision control, and effectively suppresses low-frequency vibration. There are few structural components, simple structure, high degree of integration, relatively small footprint, light weight and easy disassembly and maintenance.

Description

technical field [0001] The invention relates to a space six-degree-of-freedom magnetic suspension vibration isolation platform, which belongs to the technical field of space effective load vibration isolation. Background technique [0002] Space micro-vibration usually refers to a kind of amplitude generated by the star caused by the high-speed periodic motion of the moving parts on the star (such as flywheels, gyroscopes and other drive mechanisms) or disturbances caused by orbit changes, alternating heat and cold during the spacecraft's orbital operation. Small, wide-band flutter response. These small-amplitude and continuous micro-vibrations occurring in low frequency bands have a severe impact on the results of space microgravity experiments, and may even directly lead to the failure of some space missions. Vibration isolation technology mainly includes passive vibration isolation technology, active vibration isolation technology and active-passive hybrid vibration isol...
