In the eastern coastal and northwestern regions of our country, there are strong winds all year round and the wind force is relatively strong. In the eastern coastal areas, the economy is developed and the degree of modernization is high. With the acceleration of urbanization, the urban population has increased sharply. , in these costly land and expensive coastal cities, land resources have become very scarce, and high-rise buildings can make more full use of limited land resources, so the development of high-rise buildings is imperative.

在设计超高层建筑时，高层建筑的抗风性能是需要重点考虑的因素，而仿生建筑在提高建筑抗风性能方面有着重要的意义，如在球形鸟巢温室基础上开发的矩式鸟巢其穹顶采用流线型设计，其外观与汽车流线型相似，是减小风阻提高抗风性的仿生应用；但目前并没有针对仿生建筑的气动优化实验装置，无法精确测量流线型仿生结构表面的压力状况，无法对仿生建筑进行气动优化。When designing super high-rise buildings, the wind resistance performance of high-rise buildings is an important factor to be considered, and bionic buildings are of great significance in improving the wind resistance performance of buildings. The streamlined design, whose appearance is similar to the streamlined shape of a car, is a bionic application for reducing wind resistance and improving wind resistance; however, there is currently no aerodynamic optimization experimental device for bionic buildings, and it is impossible to accurately measure the pressure conditions on the surface of streamlined bionic structures, and it is impossible to analyze bionic buildings. Perform aerodynamic optimization.

Since the thickness of the clampingplate 19 gradually increases, thepositioning nut 20 is constantly squeezed during the movement of thepositioning nut 20 towards the movingend 21. The clampingplate 19 makes the friction force between the clampingplate 19 and thecross bar 9 bigger and bigger. When thepositioning nut 20 moves to a certain position, the friction force between the clampingplate 19 and thecross bar 9 increases to To a certain extent, the clampingplate 19 is fixed on thecross bar 9, thereby fixing the movingend 21. The clampingplate 19 itself is fixed with a rubber layer to contact thecross bar 9, increasing the distance between the clampingplate 19 and thecross bar 9.
