Abstract

The invention discloses a first-order buoyancy magnetic liquid shock absorber used in the outer space, and belongs to the field of mechanical engineering shock. The problem that an existing magnetic liquid damping shock absorber cannot be actually applied in the engineering due to various structural problems is successfully solved. The first-order buoyancy magnetic liquid shock absorber used in the outer space comprises a first limiting permanent magnet (1), a first suspension permanent magnet (2), magnetic liquid (3), a shell (4), a mass block (5), a second suspension permanent magnet (6) and a second limiting permanent magnet (7). When the outside vibrates, the mass block (5) moves in a cavity, the magnetic liquid (3) flows in the gap between a hole wall and the mass block (5) in the shell (4), and therefore energy is absorbed, and the purpose of shock absorption is realized.

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 Solar panels, antennas, etc. of the space station. However, the existing magnetic liquid damping shock absorbers cannot be applied in engineering practice due to various structural problems. The specific problems are as follows: [0003] Now the most common magnetic liquid damping shock absorber mainly adopts the second-order buoyancy princi...
