Problems solved by technology
If the pitot tube is welded to a fixed position in the wind tunnel, it will inevitably cause the pitot tube to be unable to move, and thus the height or front and rear position of the pitot tube cannot be adjusted.
[0003] However, the existing positioning platforms for wind tunnel experiments are mainly limited to short-stroke positioning, such as dispensing machines, placement machines, etc.

The invention discloses a wind tunnel wind-resistance experiment positioning platform for mounting a Pitot tube and a control system thereof. The wind tunnel wind-resistance experiment positioning platform comprises an X-axis-direction structure, a Y-axis-direction structure and a Z-axis-direction structure, wherein the Y-axis-direction structure is connected with the X-axis-direction structure and is movable in the X-axis direction. The Z-axis-direction structure is connected with the Y-axis-direction structure and is movable in the Y-axis direction. The Pitot tube is mounted on the Z-axis-direction structure and is movable in the Z-axis direction. The control system comprises a wireless panel controller and a PLC. The PLC drives an X-axis motor driver, a Y-axis motor driver, a Z-axis motor driver and a leg motor driver in a pulse mode. An X-axis motor coder, a Y-axis motor coder and a Z-axis motor coder can perform feedback of the real-time position to the PLC. The coordinate position is displayed on the wireless panel controller through control software The wind tunnel wind-resistance experiment positioning platform has advantages of long stroke, high vibration resistance and high control precision.
Description
technical field [0001] The invention belongs to the field of wind resistance experiment equipment, and in particular relates to a wind tunnel wind resistance experiment positioning platform and a control system thereof. Background technique [0002] When carrying out wind resistance experiments in wind tunnels, it is often necessary to measure fluid velocity with Pitot tubes. When measuring, the pitot tube needs to be fixed at a certain position in the wind tunnel. If the pitot tube is welded to a fixed position in the wind tunnel, it will inevitably cause the pitot tube to be unable to move, and then the height or front and rear position of the pitot tube cannot be adjusted. [0003] However, the existing positioning platforms for wind tunnel experiments are mainly limited to short-stroke positioning, such as glue dispensers and placement machines. [0004] In order to improve the testing accuracy of the pitot tube, it is necessary to provide a long-stroke positioning pla...
