Embodiment Construction

[0028] The present invention will be further described below in conjunction with the accompanying drawings.

[0029] The invention proposes a fluid damper, which uses magnetic force and a spring to push the piston in the damper to move. When the piston moves, the damping fluid flows through the small round hole (damping hole) on the piston, and the damping fluid flows through the small round hole on the piston. The hole (damping hole) consumes energy and plays the effect of controlling vibration.

[0030] The following descriptions of embodiments of the invention are merely exemplary in nature, and are in no way intended to limit the application or uses of the invention.

[0031] The present invention selects non-magnetic material, damping liquid and permanent magnet block as the basic material of the fluid damper, and the damping liquid is filled in the closed hydraulic cylinder. Specifically, the spring and magnetic force are used to push the piston to move. When the piston...

Abstract

The invention relates to a fluid damper. The fluid damper comprises an upper part and a lower part which are mutually independent; the upper part of the fluid damper comprises an upper disc flange, a first permanent magnetic block and a first pressing block, wherein the first permanent magnetic block is fixed in the upper disc flange through the first pressing block; and the lower part of the fluid damper comprises a disc, a lower disc flange arranged opposite to the disc, and a hydraulic cylinder for connecting the disc and the lower disc flange in a leakage-proof manner, wherein the lower disc flange, the disc and the hydraulic cylinder form a closed leakage-proof space. In the invention, magnetic force and a spring are used for pushing a piston to move in the damper, and when the piston moves, damping fluid flows through a small circular through hole on the piston in an energy consumption manner, so that an effect of controlling vibration is achieved.

Description

technical field [0001] The invention provides a fluid damper, which belongs to the technical field of structural vibration control. Background technique [0002] The fluid damper is an effective structural damper, but during the working process of the fluid damper, there is a possibility of fluid leakage in the fluid damper. limit. The invention provides a fluid damper, which is not prone to liquid leakage faults. Contents of the invention [0003] Technical problem: The purpose of this invention is to create a non-leakage fluid damper, which is especially suitable for structural vibration control under the condition that no leakage is allowed. [0004] Technical solution: The present invention provides a fluid damper, which includes upper and lower parts that are independent of each other. The upper part of the fluid damper includes: an upper disc flange, a first permanent magnet block, a first pressure block, The first permanent magnet block is fixed in the upper disc...
