Description
技术领域 technical field
本发明涉及结构风工程技术领域的试验装置,尤其是涉及一种风洞流场测试的排架装置。 The invention relates to a test device in the technical field of structural wind engineering, in particular to a frame bending device for wind tunnel flow field testing.
背景技术 Background technique
风洞流场调试是开展建筑结构抗风研究的前提,风洞试验段内不同高度的风速分布直接影响风洞试验的准确性。皮托管是测试平均风速最为常见的传感器,采用测压设备测试皮托管总压与静压可得到平均风速,而风洞中沿高度的风速分布则需要采用多根皮托管进行同步测试,因此有必要研制用于安装多根皮托管的装置,既要能保证皮托管安装的牢固性,又能根据试验要求进行调节。遗憾的是目前国内大多数风洞都没有一套能比较灵活地用于安装多根皮托管的装置,在流场调试中只能人为变更测试高度,来得到并非同步测试的风速分布,严重影响流场调试的精度和效率。 The wind tunnel flow field debugging is the premise of carrying out the wind resistance research of building structures, and the wind speed distribution at different heights in the wind tunnel test section directly affects the accuracy of the wind tunnel test. The Pitot tube is the most common sensor for testing the average wind speed. The average wind speed can be obtained by using the pressure measuring equipment to test the total pressure and static pressure of the Pitot tube. However, the wind speed distribution along the height in the wind tunnel needs to be tested synchronously with multiple Pitot tubes. It is necessary to develop a device for installing multiple pitot tubes, which must not only ensure the firmness of the pitot tube installation, but also adjust according to the test requirements. It is a pity that most wind tunnels in China currently do not have a device that can be used to install multiple pitot tubes more flexibly. In the flow field debugging, the test height can only be artificially changed to obtain the wind speed distribution that is not synchronized, which seriously affects Accuracy and efficiency of flow field debugging.
