Problems solved by technology

However, due to the fact that the movement speed of the model is not consistent in the test, sometimes the movement of the model will suddenly speed up, and the various postures are switched frequently, and the model is installed on the connecting end in the form of a cantilever beam, which leads to the balance and safety of the system and the model. Sexuality and other problems are more prominent, and in severe cases, there will be a break between the connecting end and the fixed end

Embodiment Construction

[0020] Such as figure 1 As shown, it is a schematic structural view of the present invention, which includes a fixed platform, a support frame is arranged on the fixed platform, and the support frame passes through the fixed platform, so that there are support frames on the upper surface and the lower surface of the fixed platform, and the lower surface is provided with a support frame. There are two support frames, the top of the support frame on the fixed platform has two support points, and a pulley is fixedly installed on the support point of each support end, and each pulley is on the same plane in space. The best stress effect, the angle between the steel cable and the steel cable bypassing the pulley is 90°. A bracket is arranged below the fixed platform, and the bracket and the fixed platform bracket are connected in the form of a slide rail, that is, a slide rail is set on the lower surface of the fixed platform, and the upper end of the bracket slides in the slide ra...

Abstract

The invention discloses a balancing device for a wind tunnel support system. The balancing device for the wind tunnel support system includes a fixing platform, a stand, a connecting rod, and a balance mechanism; the balance mechanism includes a support frame, pulleys, a steel rope, and a weight; the support frame is positioned on the fixing platform, and the upper end and the lower end of the support frame on the platform are respectively provided with two pulleys; the steel rope passes around the pulleys, and one end of the steel rope is connected to the connecting rod in a connecting base, and the other end of the steel rope is connected to the weight. According to the invention, a balancing effect, a vibration suppression effect, and a protective effect can be achieved; when a model is extremely overloaded, the model connecting rod may fall off from the stand, and the weight can pull the model connecting rod by the steel rope to protect the model against damage.

Description

technical field [0001] The invention relates to the field of wind tunnel tests, in particular to a balance device for a wind tunnel support system. Background technique [0002] During the wind tunnel test, one fixed end and one connecting end are generally used. The test model is connected to the connecting end through a balance, and then the fixed end is fixed in the wind tunnel, and the test model is tested by changing the angle between the connecting end and the fixed end. The force situation, in order to achieve the purpose of the test. In the existing wind tunnel test, there are already many supporting devices to realize the test at different angles. In the test process that can complete 6 degrees of freedom, the traditional method is to directly connect the connecting end with the aircraft model, and realize it through motor drive. The model rotates relative to a fixed point. However, due to the fact that the movement speed of the model is not consistent in the test...
