Description
Technical field
The structural seismic technical field in civil engineering is the utility model is related to, is hindered more particularly, to variable damping tuning quality
Buddhist nun's device device.
Background technology
Earthquake is one of main harm for threatening engineering structure safety, and in earthquake, the structure of building can sustain damage,
Phenomenon of caving in can be produced under serious conditions.Tuned mass damper is a kind of antishock device commonly used in current engineering structure, is adjusted
Humorous mass damper is made up of mass, spring and damping system, i.e., is adjusted its vibration frequency by spring and mass
To firmly near structure frequency, so as to change the resonance characteristics of building structure, using damping system dissipation inputted vibration energy, with
Have the function that vibration damping.Conventional tuned mass damper device is in vibration control, because external drive, structure master shake mode
And damper detuning phenomena is easily lead to during natural dynamics behaviors change, multiple tuning quality is used in engineering structure
Damper avoids detuning phenomena, but is still unable to reach optimal effectiveness in vibration suppression, it is impossible to gives full play to tuning quality damping
The damping efficiency of device.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of simple in construction, and the variable damping that effectiveness in vibration suppression is good
Tuned mass damper device.
The utility model is the technical scheme adopted is that variable damping tuned mass damper, including base and by some
The quality block assembly of mass composition stacked together, the bottom of the quality block assembly are provided with four and are used to support mass
First support base of lightweight packages, if first support base includes four supporting legs and is arranged between four supporting legs
Dried layer support frame, the first steel plate is provided with every layer of support frame, the upper surface of the steel plate carries an air
Spring, the quality block assembly also include being arranged on the second support base on the center of mass component bottom, and described the
Two support bases include upper backup pad, the lower supporting plate parallel with upper backup pad and are arranged between upper backup pad and lower supporting plate
The second steel plate and rubber slab, second steel plate and rubber slab be spaced, and the upper backup pad passes through Vertical Spring and matter
The bottom connection of gauge block component.
The beneficial effects of the utility model are：Quality block assembly, the first support base are supported by four the first support bases
Discharged by air spring and the first steel plate interval, energy caused by vibration can be consumed, improve effectiveness in vibration suppression, then in support block
The second steel plate and rubber slab that the centrally disposed stacking of component is got up, further dissipation inputted vibration energy, improves tuning matter
Measure the damping efficiency of damper.
As preferential, it is thick that the height between every layer of support frame is equal to the structure that the first steel plate and air spring are formed
Degree, can so be such that each layer of air spring and the first steel plate of last layer touches together, can improve variable damping tuning
The energy consumption effect of mass damper, improve overall effectiveness in vibration suppression.
As preferential, the bottom of the upper backup pad and the top of lower supporting plate are provided with two fixing steel plates, described
Second steel plate and rubber slab are arranged between the fixing steel plate, using this structure, primarily to improving the second support base
Stability, and reduce the second steel plate and rubber slab and the phenomenon moved left and right occur.
