Abstract
The invention belongs to the field of structural damping wind resistance of civil engineering, and discloses a damping energy-dissipation device which is suitable for reducing wind load and changing wind pressure for low-rise buildings. The damping energy-dissipation device is mainly composed of three parts, namely, an upper rotating device, a middle damping device and a lower fixing device. When wind acts on blades, the blades can rotate along with the wind, the damping effect is produced by the lower damping device to hinder rotation of the blades, and therefore the energy of wind vibration is absorbed or dissipated. The damping energy-dissipation anti-wind device is suitable for low-rise building structures of civil engineering structures, and the problem that for a huge civil engineering structure, the situation that the damping energy-dissipation property of the structure itself is utilized to resist the extraneous wind vibration action is not reliable is solved. According to the damping energy-dissipation anti-wind device, the structure is simple, the applicability is strong, and a good anti-wind effect is achieved.

Background technology
Any one engineering structures system all can produce response when being subject to extraneous interference or excitation, this is because excitation makes system obtain the input of energy.Meanwhile, system can change the energy of input into heat energy or other form of energy by certain mechanism and consume again, makes input energy and consume energy keep balance.The ability of this systems consume energy is called damping.For steady-state process, energy must be inputted continuously to system.Only have and balance each other with damping energy dissipation, the continual and steady vibration of system could be maintained.
Damping energy dissipation technology is for theoretical foundation with damping energy dissipation mechanism, the mechanism of production of damping can be divided into the material damping of engineering material, the viscous damping, collisional damping etc. of fluid by the difference of physical phenomenon, and this is mainly by being that the heat energy that can consume realizes by changes mechanical energy.At present, the main application form of damping energy dissipation technology comprises the damping of structure own material and composed of external damping device consumes energy two kinds.And additional damper has viscous damper, intelligent damper, metal damper, and the granule damper in recent years proposed.
For huge civil engineering structure, rely on the damping energy dissipation characteristic opposing of self outer the wind comes from bestir oneself with and unreliable.Along with the continuous proposition of New Damping power consumption technology, the mode utilizing structure to add outer member or inner interpolation element realizes structural vibration control mode and all embodies good control effects
Summary of the invention
In order to solve the problem, the invention provides a kind of damping wind resistance energy-dissipating device, the mock-up (as Fig. 1) of damping energy dissipation device, damping energy dissipation device is formed primarily of two parts, a part is the blade on top, and another part is the damper of bottom.When wind acts on blade, blade can rotate with the wind, and the damper of bottom can produce damping effect, hinders the rotation of blade, and then absorbs or consume the energy that wind shakes.
By multiple damping energy dissipation wind-proof device parallel series on an axis, and when wind comes, each device can independently rotate, and can not interact, and the wind field around produced also can not interact.Under the acting in conjunction of each device, reach and well change wind field and wind resistance effect.
A kind of damping energy dissipation wind-proof device, comprises blade 1, wheel hub 2, screw 3, nut 4, upper bracket 5, upper rotation pad 6, damping drum 7 (locking device), connecting rod 8, fixed head 9.
Four blades 1 are installed on the hub 2, and the intermediate cross-section of wheel hub is long-pending to be expanded, and be upper bracket 5, upper bracket 5 is connected with damping drum 7 upper surface, and the lower part of wheel hub is placed in damping drum 7; Described damping drum 7 is sealing devices, comprises lower rotation pad 10, undersetting 11, stiffener 12, through hole 13 and damping fluid 14.Corresponding four blades 1, be provided with four stiffeners 12 at damping drum 7 inwall, stiffener 12 rotates along with wheel hub 2, is full of damping fluid 14 in damping drum 7, and in rotation process, damping fluid 14 can hinder it to rotate, and reaches damping.Wearing and tearing damping drum during for preventing hub rotation, between outside upper bracket and damping drum, is respectively equipped with rotation pad 6 and lower rotation pad 10 inside damping drum and between undersetting; By fixing screw and coordinating of nut between upper bracket with undersetting; Stiffener is provided with through hole 13, and through hole, perpendicular to stiffener, allows part damping fluid to pass through; Bolt-through wheel hub, is used for fixing the top and bottom that connect wheel hub, thus strengthens its intensity.The lower surface of damping drum 7 connects connecting rod 8, and the bottom of connecting rod is connected with fixed head 9, and junction plate is used to device to be fixed on works.
The present invention has following advantage:
1, this device does not need energy to input.Wherein, the rotational of blade changes wind field blast, and damping unit can consume wind energy, is combined like this and can play good wind resistance effect, and protection roofing is not damaged.
When 2, building house, because of considering the impact of roof system form for wind loading rating power, and several specific roof system form need not be confined to, the adverse effect that installation damping energy dissipation wind-proof device brings to make up roof system form deficiency can be considered.
3, simple structure of the present invention, part is less, and simply, applicability is strong, and cost is low and easy to maintenance, effectively can improve the seismic wind resistance of structure, has wide popularization market and application prospect for making and installation process.
