The working principle of the damper 30: the pipe on which the vibration damping structure is mounted can be regarded as a two-degree-of-freedom vibration system, the main system being the pipe part 10, and the sub-system being the damper 30 of the vibration damping structure. When the operating frequency of the main system is consistent with the natural frequency of the subsystem, the energy of the main system is transferred, so that the vibration of the pipeline component 10 is absorbed by the damper 30, the pipeline component 10 is not vibrated any more, the magnet part 33 in the damper 30 starts vibrating, the relative displacement between the magnet part 33 and the conductor part 32 excites eddy currents on the conductor part 32, and the magnet part 33 is always acted by an ampere force acting against the motion direction of the magnet part 33 according to the eddy current effect, and the ampere force is the damping force acted by the magnet part 33.

4. The damper 30 is designed in a structural form that generates relative displacement with the side surface of the magnet portion 33 and the conductor portion 32 to generate eddy currents, and the first elastic member 34 and the second elastic member 35 are used as stiffness components of the magnet portion 33, so that the structural size of the eddy current tuned mass damper is greatly reduced, the damper 30 can be miniaturized, and the damper is convenient to apply to a small pipeline space.
