Existing wind field arrangement, complex structure, cost is high, and is difficult to the mean velocity profile that obtains meeting Chinese Industrial Standards (CIS) specification and turbulivity section.Debugging wind field institute spended time 3-4 days at least, 7-8 days at most, efficiency is low.And existing wind field arrangement, after parts are installed, be mostly difficult to dismounting, make a lot of wind field arrangement become disposable test unit, considerably increase experimentation cost.
Summary of the invention
In order to solve the problems of the technologies described above, the utility model provide convenience installation, combination flexibly, cost is low, the wind field arrangement that can reuse different scaling factor.
The technical solution adopted in the utility model is: comprise multiple wedge, multiple roughness element, baffle plate and lifting instrument, the even equidistant placement of described wedge, at the air port place of wind-tunnel, is connected with wind-tunnel bottom wedge; Rotating disk is provided with in wind-tunnel, multiple roughness element to be arranged in wind-tunnel between wedge and rotating disk, described baffle plate is arranged on wedge, described lifting instrument is positioned at the side of wind-tunnel inner rotary table, the cross bar of lifting instrument is provided with three-dimensional fluctuating wind speed instrument, the probe of three-dimensional fluctuating wind speed instrument, just to carrying out flow path direction, is connected with data acquisition system (DAS).
In the wind field arrangement of above-mentioned different scaling factors, described wedge is evenly arranged along the direction perpendicular to wind direction at the air port place of wind-tunnel.
In the wind field arrangement of above-mentioned different scaling factors, described roughness element is cube wooden unit.
In the wind field arrangement of above-mentioned different scaling factors, described baffle plate is rectangle baffle plate or trapezoidal baffle plate, and trapezoidal baffle plate is arranged on the bottom of wedge, and rectangle baffle plate is arranged on the middle and upper part of wedge.
Compared with prior art, the beneficial effects of the utility model are:
The utility model can utilize dissimilar triangle wedge in wind-tunnel, form the general shape of the wind profile needed for test, changes the bottom width of wedge to increase turbulivity; Can by change the size of roughness element, number and disposing way obtain testing needed for mean velocity profile and turbulivity section, can encrypt when particularly roughness element is put and put, effectively change turbulivity section; By arranging that at the bottom position of wedge trapezoidal baffle plate increases near surface turbulence degree, mean velocity profile can be changed; Can arrange that rectangle baffle plate increases the turbulivity needed for test by differing heights on wedge, and change the shape of mean velocity profile at corresponding At The Height.Under utilizing the prerequisite of the substantially passive device combination such as wedge, roughness element and baffle plate, with change flexibly its arrangement realize test needed for the mean velocity profile meeting China " loading code for design of building structures " (GB50009-2012) and turbulivity section, different scaling factor wind field can be obtained.The utility model also has the advantage that device is easy, convenience is carried, cost is low; The utility model can reuse, change flexibly, has saved the front current cost of test.
