Axial displacement amplified eddy current damper
An axial displacement amplified eddy current damper is disclosed. The axial movement of a slide bar is converted into the rotation of copper sheets and generates eddy current for energy consumption. The copper sheets are rotated and amplified by adjusting the sizes of gears. The short displacement of the slide bar can cause a large angle rotation of the copper sheets, so that energy consumption efficiency is high. The damping parameter can be adjusted by adjusting the magnetic field strength of permanent magnets, the thickness of the copper sheets and the distance from the copper sheets to the permanent magnets. The permanent magnets are adopted to provide continuous magnetic field sources, without external energy, thereby generating long-term and stable vibration reduction effect.
