Description
Technical field
The present invention relates to the test unit of Structural Wind Engineering technology, especially relate to the wedge barrier composite set of a kind of wind-tunnel boundary layer simulation.
Background technology
Wind tunnel test is a main research means of carrying out Structural Wind Engineering research, and accurately simulation of atmospheric boundary layer is to carry out the basic premise of building wind load test.Roughness element, wedge and barrier are the most common atmospheric boundary layer passive simulation devices, and roughness element is mainly used to form subaerial wind profile and turbulivity section, and wedge and barrier are mainly used to simulate the Field Characteristics of whole wind-tunnel.Regulation according to China's loading code for design of building structures, China's surface roughness type is divided into A, B, four kinds of landforms of C, D, simulate landforms and other special landforms of different scaling factors in addition according to the testing requirements needs, therefore need the geomorphic type of simulating very many in the actual engineering, this just requires the in good time changes shape of passive simulation device energy in the wind-tunnel, to adapt to the simulation needs of different landforms.Regrettably domestic most of wind-tunnel all do not have a cover can adapt to the analogue means that multiple landforms simulation requires at present, can only both cause huge waste according to the specific requirement change analogue means of each simulation, have reduced work efficiency again.
Summary of the invention
The object of the present invention is to provide the wedge barrier composite set of a kind of wind-tunnel boundary layer simulation, make it can be used in the multiple surface roughness type of simulation and other special landforms, thereby lay the foundation for carrying out the Wind Engineering test.
The technical solution adopted for the present invention to solve the technical problems is:
One side that length equals two equal angles of test chamber width is fixed on the last lower wall surface of wind-tunnel section, the outside of the another side of two equal angles is over against the flow path direction that comes of wind, the equal along its length symmetry of the another side of two equal angles has kidney slot, be vertically installed with many T steels between two equal angles, the minor face of every T steel is connected with the kidney slot inner slide of two equal angle another sides and is fixing, both sides on the long limit of every T steel are installed the right-angle triangle plank respectively, after the long limit of the long right-angle side of right-angle triangle plank and T steel is hinged, the right-angle triangle plank can inwardly overturn, below the both sides on the long limit of every T steel, in the kidney slot of equal angle glide base is installed respectively, glide base is hinged with the bearing seat that is installed in right-angle triangle plank minor face by straight-bar, has row's screw along its length at every T steel minor face.
The shape of the right-angle triangle plank that install the both sides on the long limit of described every T steel is identical.
A described every T steel minor face row along its length is equipped with that width equates or the unequal horizontal plate washer of width forms horizontal barrier in the screw.
A described every T steel minor face row along its length is equipped with width in the screw and is formed vertical barrier greater than a vertical plate washer of T steel minor face width, and vertical barrier is along wind-tunnel section center line symmetric arrangement.
The beneficial effect that the present invention has is:
The present invention combines formation one cover multifunction quilt dynamic simulated device with movable wedge and movable barrier, regulate the form of facining the wind of wedge by the link position that changes straight-bar and kidney slot, regulate blockage ratio by the quantity and the installation site that change T-steel, by different vertical plate washers and the laterally shelves wind scorpion of plate washer adjusting diverse location are installed, to adapt to the simulation requirement of different landforms.This device can improve the quality and the efficient of wind-tunnel boundary layer simulation greatly, reduces the waste of material, reaches the unification of economic benefit and social benefit.
