Embodiment Construction
[0031] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0032] refer to figure 1 , the present invention provides a turntable structure for wind tunnel test and its use method, by installing the building model on the top of the adjusting part, and then adjusting the height of several adjusting parts, so that the building model extends into the experimental cabin, and the rest A number of adjusting parts cover part of the architectural model to simulate the subsidence terrain of the architectural model, which matches the actual terrain of the architectural model, and then rotate the test bench to drive the architectural model to rotate, so as to conduct wind tunnel tests on the architectural model to solve the problem. It solves the problem that the traditional turntable cannot be applied to buildings in subsidence terrain, and can simulate the actual subsidence terrain, so as to conduct effective te...

The invention relates to a turntable structure for a wind tunnel test and a use method thereof, the turntable structure is installed in an experiment cabin of a wind tunnel, and the turntable structure comprises: a test bench rotatably installed at the bottom of the experiment cabin; and adjusting parts with adjustable heights and installed at the top portion of the test bench, whereinthe building model is installed on the tops of the adjusting parts and the heights of the adjusting parts are adjusted, so that the building model extends into the experiment module, the adjusting parts shield part of the building model so as to simulate the sinking terrain of the building model, then the test bench is rotated, and the wind tunnel test is carried out on the building model. The problem that a traditional rotating disc cannot be suitable for a building in a sunken terrain is effectively solved, the actual sunken terrain can be simulated, therefore, the whole building is effectively tested, the deviation between an experimental result and the actual situation is small, and the precision is high.
Description
technical field [0001] The invention relates to the field of wind tunnel tests, in particular to a turntable structure for wind tunnel tests and a method for using the same. Background technique [0002] The test section of the wind tunnel is equipped with a circular turntable that can rotate 360°. The three-dimensional architectural model is fixed on the top of the turntable, and the circular turntable is driven by a motor to rotate. The purpose of changing the direction of the wind. [0003] However, the traditional turntable is a simple rotating surface, and the architectural model is directly installed on the top of the turntable, which cannot be applied to buildings with sunken terrain, and it is difficult to simulate the sunken terrain, making it difficult for buildings located in sunken terrain to carry out effective tests. The results are limited and have large deviations from the actual situation. Contents of the invention [0004] The purpose of the present inv...
