Embodiment Construction

[0037] The present invention will be further described below in conjunction with the accompanying drawings.

[0038] The present invention proposes a non-leakage electromorphic damper, which uses magnetic force to push the piston in the damper to move. When the piston moves, the electromorphism flows through the small round through hole (damping hole) on the piston, and the electromorphism flows through the piston. The small round through hole (damping hole) on the top dissipates energy and plays the effect of controlling vibration.

[0039] 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.

[0040] The non-leakage current variant damper of the present invention utilizes magnetic force to push the piston in the damper to move and consume energy in a non-contact manner, and uses the current variant as a damping fluid to play an active control role.

Abstract

The invention relates to a leakage-free current variant damper which comprises a disk, a bottom disk flange arranged opposite to the disk, a hydraulic cylinder used for connecting the disk with the bottom disk flange in a leakage-free manner, a disk flange provided with a fifth aperture, and a cylinder provided with disk flanges at two opening ends, wherein the upper end of the cylinder with the disk cylinders at two ends is provided with an upper end disk flange, the lower end of the disk with the disk cylinders at two ends is provided with a lower end disk flange, and the side surface cylinder body of the cylinder with the disk flanges at two ends is provided with a circular through hole. By using a piston motion in a magnetic force traction damper, the piston moves, a current variant consumes energy when flowing through a small circular through hole on the piston, the viscosity of the current variant is changed by changing the voltage between a positive polar plate and a negative polar plate according to a vibration control requirement, and the effect of actively controlling the vibration is achieved. The damper is not easy to leak damping liquid due to no use of a dynamic sealing member.

Description

technical field [0001] The invention proposes a "non-leakage current variable damper", which belongs to the field of structural vibration control and is active 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 proposes a non-leakage current variable damper, which does not use a dynamic seal, and thus is not prone to liquid leakage faults. Contents of the invention [0003] Technical problem: The purpose of this invention is to propose a "non-leakage current variable damper", which is especially suitable for structural vibration control under the condition that no leakage is allowed. [0004] Technical solution: In order to solve the above technical problems, the technical solution provided by the present invention is: a non-leakage current variable damper, which includes: a disc, a bottom disc metho...
