Problems solved by technology

[0002] Existing studies have shown that the interaction between the test components and still air, that is, the fluid-solid coupling effect, will have a greater or lesser impact on the research results, which cannot achieve the purpose of more accurate prediction of the actual project, and at this stage there is no suitable A complete system for relevant research and analysis
In the traditional wind tunnel test, the test component is fixed in the wind tunnel for testing, and then the test component is forced to vibrate to make up for the shortcomings of the fixed test component, which will greatly reduce the test efficiency of the wind tunnel; when the test component stiffness is not At the same time, the test components need to be replaced, which also reduces the test efficiency and causes unnecessary waste in all aspects

Abstract

The invention belongs to the field of structural wind engineering and specifically discloses a novel wind tunnel test device for synchronously measuring aeroelasticity-pressure of inertia force. The test device comprises a wind tunnel body for testing a test member, a conduction member for fixing the test member, a stiffness control subsystem for changing stiffness of the test member and a data acquisition subsystem for collecting test data. The novel wind tunnel test device solves the problem that conventional wind tunnel test needs extra tests when considering fluid-solid coupling effect, and realizes test of different stiffness of members on the basis of not replacing the test member, thereby preventing waste of manpower and material resources, improving use efficiency of a wind tunneland reducing test cost.
