Coaxiality Adjustment Auxiliary Device and Adjustment Method for Installation in Large Wind Tunnel

Abstract

The invention relates to the field of large wind tunnel assembly coaxial measuring and regulating, in particular to a large wind tunnel mounting coaxiality regulating auxiliary device. The large wind tunnel mounting coaxiality regulating auxiliary device is characterized by comprising a base, a bottom plate, a movable supporting base and a measuring pointer, wherein the bottom plate is fixedly mounted on the base; three fixed blocks are fixedly arranged on the bottom plate; the three fixed blocks are arranged in the form of a right-angled U on the bottom plate, two strip-shaped holes are formed in each fixed block; the movable supporting base is rectangular, and is positioned among the three fixed blocks; bolt holes are formed in positions, which correspond to the strip-shaped holes in the fixed blocks, of the side surface of the movable supporting base; correspondingly, the bolt holes and the strip-shaped holes are connected through adjustable bolts; a circular through hole is formed in the center of the movable supporting base; and the lower end of the measuring pointer is inserted into the circular through hole. The device is used for guiding invisible measuring points inside a wind tunnel barrel body to the outer part of the barrel body to measure, so that the problem that coaxial under an invisible condition is not measured and regulated very well is solved.

Description

technical field [0001] The invention relates to the field of measurement and adjustment of large-scale wind tunnel assembly coaxiality, in particular to an auxiliary device for large-scale wind tunnel installation coaxiality adjustment and an adjustment method thereof. Background technique [0002] A wind tunnel is a wind tunnel laboratory, which is a pipe-shaped experimental device that artificially generates and controls airflow to simulate the flow of air around an aircraft or entity, and can measure the effect of airflow on entities and observe physical phenomena. , it is one of the most commonly used and effective tools for aerodynamic experiments. [0003] Wind tunnel experiments not only play an important role in the research and development of aviation and aerospace engineering, but also are indispensable in the fields of transportation, housing construction, and wind energy utilization with the development of industrial aerodynamics. In order to make the experiment...
