Abstract

The invention discloses a magnetic liquid damping shock absorber which comprises a shock absorber shell and a shock absorber mass block, the shock absorber mass block is arranged in the shock absorber shell, the shock absorber shell is a spherical shell, a non-magnetic connecting rod is arranged in the spherical shell, and the structure of the non-magnetic connecting rod is small at the upper end and large at the lower end. A first permanent magnet and a second permanent magnet are fixed to the upper end and the lower end of the non-magnetic connecting rod respectively, first magnetic liquid is arranged between the first permanent magnet and the spherical shell, and second magnetic liquid is arranged between the second permanent magnet and the spherical shell. The first magnetic liquid, the first permanent magnet, the non-magnetic connecting rod, the second permanent magnet and the second magnetic liquid jointly form a shock absorber mass block. The reciprocating motion direction of the mass block is not limited, multiple dimensions are achieved, energy dissipation and vibration reduction can be achieved no matter what posture is, and stability is good.

Description

technical field [0001] The invention belongs to the field of mechanical vibration, in particular to a magnetic liquid shock absorber. Background technique [0002] Magnetic liquid is a new type of functional material with solid and liquid properties, and the unique properties of magnetic liquid make it widely used in engineering fields. It has an irreplaceable position. The magnetic liquid damping shock absorber is a passive shock absorber, which is sensitive to inertial force, has a simple structure, small size, does not require external excitation, and is stable in use, so the magnetic liquid damping shock absorber is very suitable For low frequency, small amplitude vibration damping. When most of the existing magnetic liquid damping shock absorbers adopt a horizontally opposed structure, the reciprocating motion direction of the mass block has fewer dimensions and poor working stability. Contents of the invention [0003] The purpose of the present invention is to pro...
