Description
Technical field
The utility model belongs to structural engineering field, is related to tall and slender structure, Loads of Long-span Bridges and large span spatial structure research
Turbulent field stimulation.In engineering structure Wind Engineering research, by the air-flow at the certain angle of inclination of incoming bottom surface bulging off field, and
It is superimposed with the flow field of coming above it, can be at the same time in down wind and beam wind to the turbulent performance for producing random pulse.
Background technology
Most flowing is Turbulence Flow in nature, so wanting real mould in the Wind Engineering research of engineering structure
Draw up field of turbulent flow.At present, tall and slender structure, Loads of Long-span Bridges and long-span space are needed in the design phase by the test model of corresponding construction
Put and dynamometer check and vibration measuring experiment are carried out in artificial wind field.In Wind Engineering development test, wind-tunnel field of turbulent flow analogy method is main
Have：Using carrying out the device such as the passive simulation method of upstream arrangement roughness element, the steeple in flow field etc. and practical oscillating grid array
Active analogy method；Turbulent flow in the nature that the former passive simulation method can not be simulated sufficiently accurately, and
The shortcomings that in the presence of taking up a large area；Apparatus structure is complicated used by the active analogy method of the latter, and dismounting is difficult, for existing
The deficiency of field of turbulent flow analogy method is, it is necessary to a kind of new field of turbulent flow analogy method.
Utility model content
The purpose of this utility model is to be to provide a kind of utilize in the angled air-flow of incoming bottom surface bulging off field
To simulate the device of field of turbulent flow.The utility model can simulate required field of turbulent flow according to being actually needed so that the field of turbulent flow is more
It is close to the wind field environment residing for actual tall and slender structure, Loads of Long-span Bridges or long-span space.
To achieve the above object, the technical solution adopted in the utility model is：It is a kind of to be used for the disorderly of Structural Wind Engineering experiment
Flow field simulation device, including pedestal, air outlet pipe, air cavity, air inlet and air pump；The air cavity is arranged on base interior；Outlet
Pipe connects air cavity and pedestal outside；Air pump connects air inlet, and the air inlet is connected with air cavity；The test model is set
On pedestal.
Further, the air outlet pipe is equipped with some rows, and tilt adjustable section of the air outlet pipe in air cavity.
Further, the air inlet is equipped with several, each air inlet is all connected with an air pump.
The utility model produce beneficial effect be：The utility model is utilized in the certain air-flow of incoming bottom surface bulging off field
To simulate field of turbulent flow, so as to fulfill effective simulation to wind field residing for engineering structure, two-way arteries and veins can be simply and effectively simulated
Dynamic ground field of turbulent flow, flexible form, applicability is wide, effectively supplements with being used as prior art.

A kind of field of turbulent flow simulator front views of Fig. 2；
A kind of field of turbulent flow simulator top views of Fig. 3.
Embodiment
The utility model will be further described below with reference to the accompanying drawings.
The utility model is a kind of field of turbulent flow simulator for Structural Wind Engineering experiment, and the device is by using next
Flow field bottom surface bloats angled air-flow to simulate field of turbulent flow.
As shown in Figs. 1-3, which includes air outlet pipe 1, air cavity 2, air inlet 3, air pump 4, structural model 5 and pedestal 6, institute
The pedestal 6 stated is internally provided with air cavity 2, and the air outlet pipe 1 being arranged on pedestal 6 communicates air cavity 2 and 6 exterior space of pedestal.Base
Air inlet 3 is connected with air cavity 2 inside seat 6, air inlet 3 connects air pump 4, which is arranged on the inside of pedestal 6.
According to the needs of actual field of turbulent flow, the air pump 4, air inlet 3 and air outlet pipe 1 of varying number are set, and air outlet pipe 1 exists
Tilt adjustable section in air cavity 2.Adjustable air outlet pipe 1 makes the air-flow of ejection at a certain angle with coming flow field, so
The air-flow of ejection is superimposed with incoming, can be realized in down wind and beam wind to the turbulent performance for simulating required random pulse
Effective simulation to wind field residing for engineering structure.
In order to preferably simulate engineering structure, the utility model is carried out using structural model instead of engineering structure
Simulation.The structural model 5 of replacement is arranged on the outer surface of pedestal 6.
In the utility model, all external air pump 4 of air inlet 3 can continuous work, also variable ratio frequency changer work, make air outlet pipe 1
The air-flow of ejection has continuity or pulsating nature.
