An acceleration type eddy current inertia energy dissipator

Abstract

The invention provides an acceleration type electric eddy inert energy dissipation device. The acceleration type electric eddy inert energy dissipation device is characterized by comprising a connecting lug ring, a ball screw rod, a rotary outer barrel, a rotary nut, a coil inner barrel, a coil, a rotary permanent magnet, an additional mass block, a rotary groove, a ball, a connecting rod, a spring unit, a spring unit protection barrel and the like. The acceleration type electric eddy inert energy dissipation device has the beneficial effects that additional mass is more convenient to set and the mass synergistic agent is remarkable. Actual small mass is synergized into equivalent big mass through a synergistic mechanism, and more energy of an input structure is shared; meanwhile, the structure safety is more effectively protected, vibration energy of earthquake, wind vibration, human-induced excitation and the like are consumed, and the energy consumption performance is good; the acceleration type electric eddy inert energy dissipation device can be widely applied to the fields of earthquake (vibration) reduction and absorption and energy source infrastructures. Safe, green and efficient social and environment targets of development of China are met. An electromagnetic damping force is convenient to set and earthquake responses of the structure are effectively reduced.

Description

technical field [0001] The invention relates to an acceleration type electric eddy current inertia energy dissipator, which belongs to the technical field of energy dissipation 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. As an effective means of reducing building and infrastructure disasters, energy dissipation devices are usually divided int...

Problems solved by technology

Electromagnetic damping force means that when the conductor cuts the magnetic field lines in the magnetic field, an induced current will be generated in the conductor, and the ampere force received by the induced current always hinders the movement of the conductor, thereby providing electromagnetic damping, but generally the energy consumption efficiency is low
