Embodiment Construction

[0014] The structure of the present invention is described in detail below in conjunction with accompanying drawing:

[0015] The short-wave whip antenna fixed on the building will shake when it is affected by the wind, and the shaking of the short-wave whip antenna will deteriorate the quality of short-wave communication. Therefore, how to reduce the shaking amplitude of the short-wave whip antenna or It is a difficult problem to make it stop from the shaking state as soon as possible, so that the quality of short-wave communication can be quickly restored, and the shaking-type magneto-rheological damper of the present invention is used for vibration reduction of short-wave whip antenna. A better solution.

[0016] see figure 1 The oscillating magnetorheological damper consists of a core 26 installed in a circular tube-shaped housing 4, the housing 4 is made of a non-magnetic conductive polymer elastic material, and the core 26 has a mandrel 1 made of a non-magnetic conducti...

Abstract

The invention discloses a rocking type magnetorheological damper comprising a shell and a core part arranged in the shell, wherein the shell is in the shape of a circular tube or a circular corrugated tube, and the core part is provided with a core shaft and at least three layers of radial disks equidistantly distributed on the core shaft. The outer diameters of a topmost layer of radial disk andan undermost layer of radial disk of the core part are larger than the inner diameter of the shell and smaller than or equal to the outer diameter of the shell, and the outer diameter of a radial disk between the topmost layer of radial disk and the undermost layer of radial disk is smaller than the inner diameter of the shell. The core part is arranged in the shell, and the topmost layer of radial disk and the undermost layer of radial disk of the core part are fixed on an upper end surface and a lower end surface of the shell in a sealing way. Magnetorheological fluid or magnetorheological grease is respectively filled in the shell and gaps among all the radial disks of the core part, and magnetic field generators are arranged on the upper end surface and the lower end surface or the outer periphery of the shell.

Description

technical field [0001] The invention belongs to a magnetorheological damper, in particular to a swinging magnetorheological damper. Background technique [0002] The magneto-rheological dampers used for vibration reduction mainly include direct-acting type and rotary type. It is necessary for vibration reduction, but this will make the vibration reduction structure very complicated, and they are difficult to be independently competent for the vibration reduction occasions of shaking motion. Contents of the invention [0003] The purpose of the present invention is to provide a rocking magneto-rheological damper, which solves the situation where the existing magnetorheological damper is difficult to be independently applied to the vibration reduction of rocking motion. [0004] Technical scheme of the present invention is as follows: [0005] A rocking type magneto-rheological damper, comprising a shell and a core in the shell, the shell is in the shape of a circular tube...
