Abstract

The invention provides an adjustable damping energy storage type tuned mass damper. A damping adjusting device of a damper of consists of a permanent magnet, coils, auxiliary rods, an energy storage battery, an adjustable resistor, a light-emitting diode (LED) pre-warning indicator light; in the reciprocating motion process that the damper absorbs the vibration energy of a main structure so as to generate inertial mass, a cylindrical spiral spring provides damping, the permanent magnet generates a variable magnetic field, induced electromotive force is generated in the coils so as to generate induction current, and the induction current generates electromagnetic damping to inhibit the movement of the permanent magnet; the adjustable resistor in the damping adjusting device is adjusted, so the magnitude of the electromagnetic damping is changed, and the damping ratio of a structure reaches the optimum damping ratio; and residual energy is recovered by using the energy storage battery, the LED pre-warning indicator light provides a pre-warning indication for a pedestrian and a vehicle, and multiple effects of vibration controlling, clean energy recovery, pre-warning and alarming of vibration conditions and the like.

Description

technical field

[0001] The invention relates to a vibration damping device for suppressing structural vibration, which is especially suitable for vibration control of construction engineering structures, belongs to the technical field of engineering structure vibration damping, and specifically relates to a non-contact energy consumption, precisely adjustable damping ratio, The energy can be recovered and utilized, and it is a tuned mass damper that can suppress vibration and provide early warning for bridges or high-rise buildings. Background technique

[0002] With the continuous development of science and technology, the span of engineering structures is getting larger and higher, and the structure will generate relatively strong vibration under the action of external dynamic loads such as earthquakes or strong winds, which will increase the fatigue and damage of the structure. This leads to the failure of the structure or even catastrophic accidents before the design lif...
