Abstract

The invention provides a magnetic liquid damping shock absorber. The magnetic liquid damping shock absorber comprises a shell, a first film, a second film and a mass block assembly. A sealed cavity isdefined by the shell; the shell is provided with a first wall and a second wall which are opposite in the first direction; a first liquid cavity filled with liquid is formed in the first wall; and asecond liquid cavity filled with liquid is formed in the second wall. The first film is arranged on the first wall and covers the first liquid cavity so that the first liquid cavity can be separated from the sealed cavity through the first film; the second film is arranged on the second wall and covers the second liquid cavity so that the second liquid cavity can be separated from the sealed cavity through the second film; and the first film is a deformable film, and the second film is a deformable film. The mass block assembly is located in the sealed cavity and can abut against the first film and the second film and make the first film and the second film deform. The magnetic liquid damping shock absorber is excellent in shock absorption effect, high in shock absorption efficiency, longin service life and good in shock absorption reliability.

Description

technical field [0001] The invention relates to the field of mechanical engineering vibration control, in particular to a magnetic liquid damping shock absorber. Background technique [0002] Magnetic fluid is a new type of functional material with fluidity and magnetism, and its unique properties make it widely used in engineering fields. 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. Therefore, the magnetic liquid damping shock absorber is widely used in the low-frequency, small-amplitude vibration reduction of long straight objects of large spacecraft (such as solar panels and antennas of space stations, etc.). At the same time, it also has broad application prospects on the ground, such as vibration reduction of high-power antennas up to 100 meters long, vibration reduction of precision balances, and so on.
