Embodiment Construction

[0037] The invention proposes a non-leakage current variant electromagnetic fluid damper, which uses magnetic force to push the piston in the damper to move. When the piston moves, the current variant flows through the small round through hole (damping hole) on the piston, and the current variant flows Energy is dissipated when passing through the small round hole (damping hole) on the piston, which has the effect of controlling vibration.

[0038] 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.

[0039]All springs all take circular spring form, and the upper surface of piston 18 has second T-shaped quadrilateral groove 29, and the length direction line of the second T-shaped quadrilateral groove 29 passes the circle center of piston 18, and the second T-shaped quadrilateral groove 29 is evenly distributed on On the piston 18, all the second T-shaped quadran...

Abstract

A leakage-free electromagnetic fluid damper with electro-rheological fluids comprises a disk (13), a bottom disk flange (23), a hydraulic cylinder (14), a disk flange (1) and a cylinder (9) with an opening, wherein the bottom disk flange (23) is opposite to the disk (13), the hydraulic cylinder (14) is used for leakage-free connection of the disk (13) and the bottom disk flange (23), the disk flange (1) is provided with a third unthreaded hole (25), two ends of the cylinder (9) are provided with disk flanges, the upper end of the cylinder (9) is provided with the upper end disk flange (12), the lower end of the cylinder (9) is provided with the lower end disk flange (10), and a lateral cylinder body of the cylinder (9) is provided with a circular through hole (56). When a piston in the magnetic traction damper moves, the electro-rheological fluids flow through a small circular through hole on the piston and simultaneously consume energy, and the viscosity of the electro-rheological fluids is changed by changing voltage between a positive plate and a negative plate according to the requirement on vibration control, so that vibration can be actively controlled.

Description

technical field [0001] The invention proposes "a non-leakage current variable electromagnetic fluid 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 electromagnetic fluid 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 variant electromagnetic fluid 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 invention is: [0005] The piston moveme...
