Problems solved by technology

However, the magnetic liquid damping shock absorber in the existing related art still has problems such as single energy consumption form, unsatisfactory damping effect, and low vibration damping efficiency, which restricts the actual production and application of the magnetic liquid damping shock absorber.
Moreover, when the magnetic liquid damping shock absorber is subjected to a large acceleration, the vibration damping mass is likely to rigidly collide with the shell, causing vibration reduction failure, and even affecting the service life of the magnetic liquid damping shock absorber

Abstract

The invention provides a magnetic liquid damping shock absorber, which comprises a housing, a first membrane, a second membrane, and a mass block assembly. The casing defines a sealed cavity, the casing has a first wall and a second wall opposite in a first direction, a first liquid chamber filled with liquid is formed on the first wall, and a liquid cavity filled with liquid is formed on the second wall. Second liquid chamber. The first film is arranged on the first wall, and the first film covers the first liquid chamber so that the first liquid chamber is separated from the sealed cavity by the first film. The second film is arranged on the second wall, and the second film covers the second liquid chamber so that the second liquid chamber is separated from the sealed cavity by the second film, wherein the first film is a deformable film, and the second film is a deformable film. A mass assembly is positioned in the sealed cavity, the mass assembly being capable of abutting against and deforming each of the first and second membranes. The magnetic liquid damping shock absorber has excellent vibration reduction effect, high vibration reduction efficiency, long service life and good vibration reduction 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, magnetic liquid damping shock absorbers are widely used in the low-frequency, small-amplitude vibration reduction of long and 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.
