Description
Technical field
The utility model relates to the wind loading rating testing apparatus of object, relates in particular to a kind of unitized construction thing sections model wind tunnel testing apparatus.
Background technology
The wind loading rating of objects such as test architecture thing provides foundation for the design of objects such as buildings.The aerodynamic force proving installation majority of present objects such as the actual buildings of simulation is that the sections with its structure is that model carries out the wind resistance test, and the aeroelastic model testing expenses are very high, and the sections of so-called structure is the rigid model of the representational a part of sections of structural elements of objects such as buildings.During test the sections model is placed wind-tunnel, under wind action, the suffered aerodynamic force effect of test sections model.
Existing wind loading rating proving installation has only been simulated suffered aerodynamic force (wind load) effect of object such as buildings or structures in open landforms, the buildings around such proving installation has been ignored or the mutual aerodynamic influence of structures.Studies show that, the result who is measured on wind load that acts on the buildings in the actual environment and the isolated buildings is also inequality, the existence of adjacent building, with its geometric configuration, planimetric position, relatively incoming flow towards and the equal various factors of upstream geomorphological environment, the charming appearance and behaviour acting force that acts on the buildings is exerted an influence.
The utility model content
The purpose of this utility model provides a kind of unitized construction thing sections model wind tunnel testing apparatus, when this testing apparatus can be simulated adjacent objects and exists, the suffered air aerodynamic force effect of object such as buildings in the actual environment, its test result is more accurate, and more reliable guarantee can be provided for the design of objects such as buildings; The utility model apparatus structure is simple, and is easy to operate.
The technical scheme that its goal of the invention that realizes the utility model adopts is:
A kind of unitized construction thing sections model wind tunnel testing apparatus, its composition is: all be fixed with circular slide bar on the end plate on facing the wall and meditating in the two ends that are installed in wind-tunnel, and the center of circular slide bar is provided with the force balance that links to each other with works sections model to be measured; Be with four circular slide bar collars on the circular slide bar, be with two straight slide bar collars on two straight slide bars respectively, hinged on the circular slide bar collar on the straight slide bar collar and the circular slide bar by rivet; And be equipped with lock-screw on the circular slide bar collar and the straight slide bar collar.
The utility model course of work and principle of work are:
When testing the aerodynamic force of works sections model of objects such as a certain buildings when needs, the two ends of this works sections model (tested sections) are linked to each other with the force balance at circular slide bar center on the two end plates respectively, simultaneously, by the slip on the straight slide bar collar of the circular slide bar collar, straight slide bar can be adjusted to the position that needs in slip on the circular slide bar and straight slide bar; Tighten lock-screw then, make the stationkeeping of the circular slide bar collar on circular slide bar, the stationkeeping of straight slide bar on the straight slide bar collar, thus make straight slide bar and go up the stationkeeping of the environment sections that connects.And then will simulate adjacent objects in the surrounding environment the two ends of one or two environment sections model (environment sections) connect respectively on the two end plates one or the two straight slide bars, promptly finish the installation of tested sections model and environment sections model, thereby in the wind tunnel test device, form the unitized construction thing of tested sections model and environment sections model formation.
During wind-tunnel work, the suffered wind load of tested sections is all passed to force balance.The suffered wind load of other environment sections then reaches the wind-tunnel wall by the straight slide bar on the end plate.Thereby the aerodynamic force that the power that force balance is measured only is subjected to for tested sections, since the environmentally advantageous simulation of tested sections in wind-tunnel the adjacent objects in the true environment, the aerodynamic force of measuring like this is that tested sections is subjected in the environment other object influence and the true aerodynamic force state when disturbing, thereby test result is more true and reliable.
When needs adjust environment sections and tested sections and the adjacent position time, by adjusting the position realization of straight slide bar on circular slide bar:
When needs change the horizontal level of environment sections, unclamp the screw of tightening on the straight slide bar collar, allow straight slide bar and environment sections thereof along straight slide bar collar horizontal slip, tighten again, can realize that the variation of the horizontal level of environment sections reaches fixing.
When needs change the upper-lower position of environment sections, unclamp the screw of tightening on the circular slide bar collar, make the circular slide bar collar vertical moving on circular slide bar, thereby the environment sections on straight slide bar is changed with respect to tested sections upper-lower position.
Certainly, straight slide bar and environment sections thereof also can rotate around the center of circular slide bar under this state, thereby simulate the different angles between tested sections and the environment sections.
Compared with prior art, the beneficial effects of the utility model are:
The collar by fit on circular slide bar and the straight slide bar is again with being movably connected of circular slide bar of the hinged realization of two collars and straight slide bar, thus can adjust easily environment sections on the straight slide bar that the tested sections at circular slide bar center is adjacent about, position, the left and right sides and angle of inclination thereof.Like this, when the adjacent objects that the utility model can be simulated all places and angle exists, to the air aerodynamic influence that tested sections produced, thereby make the actual suffered aerodynamic force of the testee in its test result and the true environment more approaching, foundation more accurately and reliably can be provided for the design of objects such as buildings.
The utility model is simple in structure, and is easy to operate, and comparing with conventional static(al) test macro has only increased the less slide bar of front face area, little to the disturbance of air flow in the wind-tunnel.
Below in conjunction with accompanying drawing and concrete embodiment the utility model is described in further detail.
