Abstract
Description
技术领域technical field
本实用新型涉及一种适配于低湍流度低速风洞的万向镜。The utility model relates to a universal mirror adapted to a low-turbulence and low-speed wind tunnel.
背景技术Background technique
在低湍流度低速风洞的PIV(Particle Image Velocimetry,粒子图像测速法)试验中,现有的反光镜片使用方法是直接将其用胶带固定在试验闭合段外壁上,通过在反光镜的周围加垫不同高度的纸张以调整其角度,以达到反射光线与原光线在同一水平位置的效果,该方法下,反光镜片角度极易改变,且在试验过程中,频繁调整反光镜片的效率非常低,还会影响试验数据的精确度,其原因主要在于:胶带粘贴及加垫纸张的不牢固性,尤其是在较高风速下风洞产生的震动对反光镜片角度影响非常大,并且,胶带的粘贴方式及胶带粘胶的清理,对频繁更换镜片的需要也会产生很大的影响。In the PIV (Particle Image Velocimetry, particle image velocimetry) test in the low-turbulence and low-speed wind tunnel, the existing method of using the reflector is to directly fix it on the outer wall of the closed section of the test with adhesive tape, and by adding tape around the reflector Pad paper with different heights to adjust its angle, so as to achieve the effect that the reflected light and the original light are in the same horizontal position. Under this method, the angle of the reflector is very easy to change, and during the test, the efficiency of frequently adjusting the reflector is very low. It will also affect the accuracy of the test data. The main reasons are: the weakness of the adhesive tape and the padded paper, especially the vibration generated by the wind tunnel at high wind speeds has a great influence on the angle of the reflector, and the adhesive tape is pasted. The method and cleaning of the adhesive tape will also have a great impact on the need for frequent lens replacement.
