Description

Adjustable TMD damping unit
Technical field
The utility model relates to the damping unit of a kind of damping unit, particularly a kind of frequency adjustable.
Background technology
The effect of earthquake and wind load often makes high-rise and superelevation layer structure and bridge, vestibule because the bigger influence and the destruction of expansion effect generation of energy, in order to reduce influence and destructiveness, often need structurally to install some damping energy-dissipating devices, the most typical energy-dissipating device is exactly a damper.The phenomenon that has damping leakage of oil and so on that can not well absorb vibrational energy, have that has of Chang Yong damper in the market, and similar damper on the overseas market, requirement on machining accuracy is very high, and is very expensive.Crossover or vestibule for large span, it is except earthquake and wind action, the people is normal, and walking is the main cause that causes vibration, and the frequency of people when walking is often approaching with the natural frequency of crossover or vestibule, so the stream of people by the time cause resonance easily, if resonance frequency within the sensitive range of human psychological sensation, will exert an influence to people's comfort level.This just needs a kind of energy-dissipating device, should satisfy the requirement of these operating modes, also wants simultaneously well to absorb the energy that vibration produces, to satisfy the actual comfort level requirement of using.
Summary of the invention
The purpose of this utility model provides a kind of novel adjustable TMD damping unit, solve the technical problem of crossover or vestibule energy-dissipating and shock-absorbing; And the existing damper structure complexity of solution, the problem that involves great expense.TMD is that Tuned Mass Damper is the general abbreviation of tuned mass damper, TMD.
For achieving the above object, the utility model adopts following technical scheme: a kind of adjustable TMD damping unit, comprise top board, base plate, viscoelastic damper, spring and mass, described mass is fixed as one by bolt and base plate, described spring is four, spring inner is installed with spring guide, spring guide is clipped between top board and the base plate in two separate ranks, between the bottom surface of spring guide and the plate upper surface slit is arranged, and be connected by bolt with base plate, be connected by screw A with top board, described viscoelastic damper is positioned at the space center that four springs are formed, and the top of viscoelastic damper is connected with a bulb, and the axle bulb is connected by flange with axle bulb outer cover, axle bulb outer cover is fixed by screw B and top board, and the bottom of viscoelastic damper is connected by bolt with base plate.
Be lined with packing ring between the nut of described bolt and the base plate.
Described packing ring is lockmaking packing ring or bonded washer.
The height of described mass is less than the height of viscoelastic damper.
Described viscoelastic damper is formed by interior steel pipe and outer steel pipe intussusception, between the two-layer steel pipe viscoelastic material is arranged, and the cross section of described interior steel pipe and outer steel pipe is the ladder variable cross-section, and the bottom diameter of section is greater than the tip section diameter.
The global stiffness of described spring is 91.3KN/M ± 10%, and the gross mass of described mass is 440 ± 50KG.
Described top board is reserved with connecting hole in spring outward flange position, and two connecting hole middle positions are reserved with lifting eye.
Compared with prior art the utlity model has following characteristics and beneficial effect:
1) the related adjustable TMD damping unit of the utility model, it is good to subtract gust energy-dissipating property.Under extraneous incentive action, damping unit can respond rapidly, absorbs energy, and bigger power consumption effect is arranged, the effect of performance favorable damping, and the structural vibrations response is set behind the damping unit to be had more significantly and reduces, and energy-dissipating property is good.
2) the utility model damper frequency adjustable.Change by spring rate and mass quality can realize the damping unit frequency adjustable, when reality is used, can design different spring rates according to actual conditions and satisfy the different power consumption requirement of different parts with the mass quality.
3) the utility model simple structure is easy for installation The member that adopts is building unit commonly used, installs very conveniently, during installation, only needs connector welded with the cover plate of damping unit or anchor ear shape is connected and gets final product.And the damping unit volume is little, and is in light weight, manually can operate, and greatly reduces installation cost, improved efficient.
The utility model has overcome traditional damping unit complex structure, involves great expense, and the unfavorable shortcoming of energy-dissipating property has solved the technical problem that realizes good energy-dissipating property and damping unit frequency adjustable by simple structure.
The utility model can be widely used in the shock insulation of high-rise super highrise building and bridge and crossover or vestibule.
