Abstract

The invention discloses a magnetic liquid shock absorber, which comprises a shell, a first shock absorbing assembly and a second shock absorbing assembly, the shell has a first chamber, the first chamber is filled with magnetic liquid, and the first shock absorbing assembly is located at In the first chamber, the first damping assembly includes a housing, a first permanent magnet and a second permanent magnet, the housing has a second chamber, the second chamber is filled with magnetic liquid, the first permanent magnet and the second permanent magnet The magnets are arranged oppositely in the height direction of the shell, and the housing is located between the first permanent magnet and the second permanent magnet in the height direction of the shell; the second vibration damping assembly is located in the second chamber, and the second vibration damping assembly includes the first A magnetic levitation component, a third permanent magnet and a fourth permanent magnet, the third permanent magnet and the fourth permanent magnet are arranged oppositely in the length direction of the casing, and the first magnetic levitation component is located between the third permanent magnet and the fourth permanent magnet in the length direction of the casing Between the fourth permanent magnet. The magnetic liquid damper of the present invention can improve the damping efficiency.

Description

technical field [0001] The invention relates to the technical field of vibration reduction, in particular to a magnetic liquid shock absorber. Background technique [0002] As a new type of nanomaterial, magnetic fluid is widely used in sealing, sensing, vibration reduction and other fields. Under the action of a magnetic field, a magnetic liquid can suspend an object with a density greater than it. This property is called the first-order buoyancy principle of the magnetic liquid; a magnetic liquid can suspend a permanent magnet immersed in it, and this property is called a magnetic liquid. The principle of second-order buoyancy. In the related art, the magnetic liquid vibration damping device only utilizes the first-order or second-order buoyancy principle of the magnetic liquid, and the vibration damping efficiency is low. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the related art at least to a certain extent...
