Three-dimensional movement test device for wind tunnel

Abstract

The invention discloses a three-dimensional movement test device for a wind tunnel. The three-dimensional movement test device is formed by an X-axis moving mechanism, a Y-axis moving mechanism and a Z-axis moving mechanism, wherein the Y-axis moving mechanism is divided into a first Y-axis moving mechanism and a second Y-axis moving mechanism which are synchronous moving mechanisms, so that up-and-down movement in a vertical plane is realized; the Z-axis moving mechanism is divided into a first Z-axis moving mechanism and a second Z-axis moving mechanism which are respectively arranged on the Y-axis moving mechanism and are connected through grid plates, so that left-and-right movement in a horizontal plane is realized; the X-axis moving mechanism is arranged in the wind tunnel and is fixedly connected between the two grid plates, so that front-and-back movement in a horizontal plane is realized; and when the X-axis moving mechanism, the Y-axis moving mechanism and the Z-axis moving mechanism work integrally, the movement and the accurate positioning of a probe in a three-dimensional space in a flow field are realized, the testing efficiency in the flow field is improved, parameters on any point or a curve in the space in the flow field can be tested, and the accuracy of the test parameters is improved.

Description

technical field [0001] The invention relates to a testing device, in particular to a three-coordinate moving testing device used in a wind tunnel. It belongs to the technical field of mechanical design and manufacturing and automatic testing. Background technique [0002] Flow field is the spatial area occupied by moving fluid. Flow field experiments are widely used in aviation, aerospace, shipbuilding, automobile industry and wind power, hydropower, nuclear power technology fields. In scientific research and production applications, it is often necessary to test various parameters of the experimental model in the flow field. [0003] At present, there are two test methods in the flow field. One is to place the test instrument in the flow field and move the test instrument artificially according to the demand, so as to achieve the purpose of multi-point test. The other is to use a test device with a higher degree of automation, and place the test device in a closed flow fi...
