Inertial electrical eddy current tuning and damping device

Abstract

An inertial electrical eddy current tuning and damping device is used for houses, bridges, large-span spatial structures and other engineering structures comprises a mass block, at least one vertical spring connected with the mass block and at least one acceleration-type electrical eddy current inertia damper connected with the mass block, wherein the spring and the acceleration-type electrical eddy current inertia dampers are arranged between a body structure and the mass block in parallel. Under the vertical effects of vertical earthquakes, human-induced excitation, running vehicle excitation and the like, the compressed spring extends, mass tuning and damping is achieved in the vertical direction through the mass block providing a reserve acting force for a connecting structure. The acceleration-type electrical eddy current inertia damper absorbs energy through two node mass units. Compared with traditional turning mass dampers, the mass required by the mass block is effectively decreased, and the vibration amplitude of the mass block is effectively controlled through an electrical eddy current damping units consuming energy.

technical field [0001] The invention relates to an inertial electric eddy current tuning damping device, which belongs to the technical field of energy consumption and shock absorption of civil engineering structures. Background technique [0002] Energy dissipation and vibration reduction technology is to add energy dissipation and vibration reduction devices to the structure. The additional vibration reduction devices and the structure itself bear the effects of earthquakes and wind vibrations. The dynamic response of the structure itself is reduced through the energy dissipation of the additional vibration reduction devices. Functional requirements such as safety, comfort and normal usability of the structure are guaranteed. Scholars at home and abroad have done a lot of research on energy dissipation and vibration reduction technology, in which mass tuning devices are usually attached to the main body of the building structure, and mass blocks, tuning springs and damping...

AI Technical Summary

Problems solved by technology

[0003] In the existing design of traditional mass-tuned damping devices, in order to meet the vibration reduction target of the structure under the action of vertical vibration, the mass block is large in size and difficult to install (this is a common problem in the vertical vibration control of building structures at present. problem), it is not convenient to adjust the tuning frequency of the damping device, setting it on the structure not only increases the structural load but also poses a safety hazard
