Embodiment Construction

[0019] Below in conjunction with accompanying drawing and example describe structure of the present invention in detail:

[0020] Vibration reduction of large-span steel cables has always been a difficult technical problem in the industry. When the axial extension of the steel cable is not considered, the radial vibration of the steel cable is a complex two-dimensional plane vibration. The two-dimensional magnetorheological damping of the present invention The vibration damper can be used to solve this kind of vibration.

[0021] see figure 1 , the core 2 made of highly magnetically permeable material is embedded in the shell 1 made of nonmagnetically permeable material.

[0022] The core 2 has a mandrel 201 and two layers of radial discs 202 equidistantly distributed on the mandrel. The center of the mandrel 201 has a through hole 3 for radially constraining the steel cables.

[0023] The casing 1 is cylindrical with a central through hole, and a layer of radial concave cav...

Abstract

The invention discloses a two-dimensional magnetorheological damper which comprises a shell and a core part, wherein the middle of the shell is provided with a concave cavity and an equal-diameter through hole which is arranged in the axial direction of the shell; the core part is installed in the equal-diameter through hole of the shell; the middle of the core part is embedded into the concave cavity of the middle of the shell; gaps are reserved between the inner circumferential surface of the shell and the outer and the inner circumferential surfaces of the core part and between the concavecavity of the middle of the shell and the upper and the lower surfaces of the core part; the gaps are filled with magnetorheological fluid or magnetorheological resin; a magnetic field generator is installed on the shell or / and the core part; the core part in the shell can move arbitrarily in a radial direction; and the magnetic field intensity outputted by the magnetic field generator is regulated to change the viscosity of the magnetorheological fluid or the magnetorheological resin in the shell and the damping force when the core part moves arbitrarily in the radial direction and to control the damping force of the two-dimensional magnetorheological damper.

Description

technical field [0001] The invention relates to the technical field of magnetorheological dampers. Background technique [0002] The existing published magnetorheological dampers are mainly divided into two categories: one is linear, and the other is rotary. These two types of magnetorheological dampers have their clear scope of application, such as rotary magnetic flow The variable damper is suitable for vibration reduction of various rotary motions, while the linear magneto-rheological damper is suitable for vibration reduction of reciprocating motion. Due to the limitation of their structure, these two types of magnetorheological dampers cannot be independently applied It is used in the vibration reduction of two-dimensional plane motion. Contents of the invention [0003] The purpose of the present invention is to propose a two-dimensional magneto-rheological damper, which solves the situation where the existing magnetorheological damper cannot be independently applie...
