Problems solved by technology

Wind tunnels have the characteristics of adjustable wind speed and stable flow field. However, wind tunnels usually require a long construction period, high construction costs and operating costs. At the same time, the location of the wind tunnel is fixed, energy consumption is large, and noise is large.
Due to these unfavorable factors, the popularization of wind tunnel test methods is limited; flight tests and wind field tests also have time-consuming and expensive problems

Embodiment Construction

[0006] Such as figure 1 As shown, the aeroelastic vehicle-mounted test platform system according to an embodiment of the present invention includes: vehicle subsystem (1), data measurement and control subsystem (2), model support subsystem (3); wherein, data measurement and control subsystem (2 ) and the model support subsystem (3) are installed on the vehicle subsystem (1), and the test model (4) is installed on the model support subsystem (3).

[0007] The data measurement and control subsystem (2) and the model support subsystem (3) are carried by a car, and the car itself constitutes the vehicle subsystem (1). The basic test state is that the car drives at a certain speed at a constant speed to generate flow speed.

[0008] The platform is intended for various test models where aerodynamic or aeroelastic problems may occur (4). The test model (4) is installed on the roof of the vehicle through the model support subsystem (3) to simulate the incoming flow conditions of th...

Abstract

The invention discloses a vehicle-mounted aeroelastic test platform system, and provides a comprehensive test platform system for model support, air flow generation and adjustment and movement test in an aeroelastic test. The vehicle-mounted aeroelastic test platform system adopts a test model in aeroelasticity (static aeroelastic divergence, vibration, aeroservoelasticity and the like) researching or other aerodynamics researching as an application object, and can be used for the blowing tests such as the principle exploring, performance test, theory verification and the like of aeroelasticity or aerodynamics. The whole system comprises a vehicle subsystem, a data test and control subsystem and a model support subsystem.

Description

technical field [0001] The invention relates to an aeroelastic vehicle test platform system. It can be used to simulate the flight or operating state of the test model, so as to verify and test the aeroelastic principle and performance of the test model. Background technique [0002] The structure exposed to the airflow has a certain degree of elasticity, and the mutual coupling of the elastic force, inertial force and aerodynamic force of the structure will cause aeroelasticity problems. Such problems widely exist in aircraft, wind turbines, high-rise buildings and other structures. Traditional mechanical analysis methods do not consider the coupling effect of elastic force, inertial force and aerodynamic force. The real situation is that when these three are unfavorably coupled, the structural stability decreases, and in severe cases, instability occurs. Among them, only the instability coupled with aerodynamic force and elastic force is called static aeroelastic diverge...
