Abstract

The invention relates to a magnetic liquid damping shock absorber with a magnetic straight line, and belongs to the field of vibration of mechanical engineering. Magnetic liquid is adsorbed on two ends of a columnar permanent magnet selected by the shock absorber; the columnar permanent magnet is in a suspension state in a non-magnetism-conducting round pipe, and responds to external vibration as an inertial mass block; the movement state of the columnar permanent magnet is controlled by an external permanent magnet sheet which is in rigid connection with the non-magnetism-conducting round pipe; the columnar permanent magnet as the inertial mass block moves at the center position in a reciprocating manner by restoring force provided by the attraction force between permanent magnet materials under the action of external vibration; the magnetic liquid moves along with the columnar permanent magnet, and is extruded by a corrugated inner wall of the non-magnetism-conducting round pipe in order in the movement process, so as to consume energy and absorb shock. The damping shock absorber is simple in structure, high in reliability and excellent in damping effect.

Description

technical field [0001] The invention relates to a magnetic linear magnetic liquid damping shock absorber, which belongs to the field of mechanical engineering vibration. Background technique [0002] Magnetic liquid vibration damping is a new type of vibration damping method, which is highly sensitive to inertial force, and has the advantages of simple structure, small size, large energy consumption and long life, and can meet some local vibration damping requirements in spacecraft . Some long objects in the spacecraft have local vibration problems during the application process. This kind of local vibration often shows the characteristics of low frequency, small displacement and small acceleration. Compared with magnetic liquid damping shock absorbers, other vibration reduction methods are difficult to meet Require. [0003] The application process of the magnetic liquid damping shock absorber is often designed according to the specific application environment. After the ...
