Interlaminar shear amplification type eddy current damper
The invention belongs to the technical field of structural vibration control, and provides an interlaminar shear amplification type eddy current damper. The interlaminar shear amplification type eddy current damper can effectively control vibration of a high-rise building under the action of an earthquake, reduce deformation between structural layers and guarantee safe operation of a building structure. An eddy current technology is adopted for energy consumption, the lever principle is utilized for adjusting the force arm ratio to amplify vibration displacement, and the energy consumption efficiency is greatly improved. Damping parameters can be adjusted by adjusting the distance ratio of a screw to a steel bar and a copper sheet, the magnetic field intensity of a permanent magnet, the thickness of the copper sheet and the distance between the copper sheet and the permanent magnet. The permanent magnet is adopted for providing a continuous magnetic field source, external energy is not needed, and a long-term stable vibration reduction effect can be generated. A magnetic conductive material is adopted, magnetic leakage of a magnetic circuit can be effectively avoided, the eddy current damping efficiency is improved, and influences on various surrounding components are avoided. The interlaminar shear amplification type eddy current damper is reasonable in design, simple in structure and convenient to install and maintain.
