Abstract

The invention relates to a cylindrical first-order buoyancy magnetic liquid vibration absorber, and belongs to the field of mechanical engineering vibration. The cylindrical first-order buoyancy magnetic liquid vibration absorber successfully solves the problem that an existing magnetic liquid clamping vibration absorber cannot be applied in engineering practice caused by multiple structures. The cylindrical first-order buoyancy magnetic liquid vibration absorber comprises a first limiting permanent magnet (1), a shell (2), an upper V-shaped armature (3), the magnetic liquid (4), a mass block (5), a second limiting permanent magnet (6), a lower V-shaped armature (7), a first suspension permanent magnet (8), a second suspension permanent magnet (9), a third suspension permanent magnet (10) and a fourth suspension permanent magnet (11). When the outer side words vibrated, the mass block (5) moves in a cavity, and the magnetic liquid (4) flows in a gap between the inner hole wall of the shell (2) and the mass block (5), so that energy is absorbed, and the purpose for reducing vibration is achieved.

Description

technical field [0001] The invention belongs to the field of mechanical engineering vibration. Background technique [0002] The magnetic liquid damping shock absorber is a passive shock absorber with high sensitivity to inertial force, and has the advantages of simple structure, small size, large energy consumption and long life. Due to the special operating environment of the spacecraft, its own volume, weight and energy carried are limited to a certain extent, so the magnetic liquid damping shock absorber is very suitable for the low-frequency, small-amplitude vibration reduction of long straight objects in large spacecraft, such as The solar panels and antennas of the space station also have broad application prospects on the ground, such as the vibration reduction of high-power antennas up to 100 meters long, the vibration reduction of precision balances, and so on. However, the existing magnetic liquid damping shock absorbers cannot be applied in engineering practice ...
