Quick pull-out tool of wind tunnel force measurement test model, and application thereof

Abstract

The invention discloses a quick pull-out tool of a wind tunnel force measurement test model, and an application thereof, and belongs to the field of wind tunnel tests. The problem that a universal quick pull-out tool suitable for the wind tunnel force measurement test model lacks on the current market is solved. The quick pull-out tool comprises a cross beam, a connecting screw and pull-out components, and the connecting screw passes through the cross beam, and the connecting screw is in threaded connection with the cross beam; and a group of pull-out components is provided, the pull-out components are connected with the cross beam, and the pull-out components are arranged on both sides of the connecting screw. By adopting of the quick pull-out tool disclosed by the invention, the model can be quickly separated from a model supporting rod to achieve the purpose of pulling out the model. By adopting of the quick pull-out tool disclosed by the invention, a worker can observe the deviation process in naked eyes in a screwing process to ensure that the deviation process is safer and more reliable, and the efficiency is greatly improved. In addition, the quick pull-out tool is suitablefor 90% force measurement test models of wind tunnels, thereby having high adaptability. The quick pull-out tool disclosed by the invention is ingeniously designed, reasonable in design and convenientto use, has a high application value and a good application prospect.

Description

technical field [0001] The invention relates to the field of wind tunnel tests, in particular to the field of wind tunnel test mechanical structures, in particular to a quick-drawing tool for a wind tunnel force measurement test model and an application thereof. Background technique [0002] Before the wind tunnel test, the test model needs to be installed on the wind tunnel support rod. For the force-measuring test model, the front end of the support rod will be connected with a force-measuring balance; because the wind tunnel test balance is a high-precision equipment, it is not allowed to open model tension holes at the steps on both sides of the balance, only on the central axis of the balance. The model tension hole, so the balance and the model tension need to add a transitional copper sleeve to prevent the model from rolling during the blowing test, which will affect the safety of the model and the safety of the test data. The larger the model, the greater the tensio...
