Abstract

The invention discloses a double-layer circular-tube type axial-force eddy current damper, which consists of an eddy current damping system, a guiding system and a connecting system, wherein the eddy current damping system is composed of a circular magnet and a double-layer circular tube, the double-layer circular tube comprises an outer circular tube made of strong magnetic-conducting material and an inner circular tube made of strong electricity-conducting magnetic-isolating material through nesting; the guiding system consists of a guiding ring, an inner guiding shaft and a hollow round support column, has inner-layer and outer-layer guiding functions, and also can have one guiding function according to the condition; and the connecting system is composed of a connecting block at the upper end of the double-layer circular tube and a support base at the lower end of the circular magnet. With the adoption of the specific double-layer circular tube design, the damper is only provided with one group of circular magnets on the inner side of an electric conductor tube, all magnetic-force lines can vertically cut the circular tube in the electric conductor and cannot be distributed outside the double-layer circular tube, and achieves the purposes of improving the eddy current efficiency and shielding the magnetic field outwards.

Description

technical field [0001] The invention mainly relates to an axial force damper utilizing the principle of eddy current, and belongs to the technical field of structural vibration control. [0002] Background technique [0003] Dampers dampen vibrations from tiny instruments to giant structures. The eddy current damper is a vibration damping device with superior performance and great development prospects. The basic principle of eddy current is: when the conductor cuts the magnetic force line, an eddy current will be generated in the conductor, resulting in a resistance heating effect to consume vibration energy; the eddy current will generate a new magnetic field opposite to the direction of the original magnetic field, thus generating a new magnetic field in the direction opposite to the direction of the conductor's motion. The opposite damping force plays a role in reducing vibration and energy consumption. Compared with some existing damping devices, it does not rely...
