Embodiment Construction

[0030] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:

[0031] Such as figure 1 , 2 As shown, the test device for the first corner section of the automobile wind tunnel of the present invention includes: a steel runner collection port, a corner guide vane 3, and a guide vane lifting device.

[0032] Specifically, the collecting port of the steel flow channel includes an air inlet section 1 and an air outlet section 2, and a corner deflector 3 is arranged between the air inlet section 1 and the air outlet section 2, and the corner guide vane and the air inlet section and the air outlet section There is a certain gap between them, and there is no connection between the three, and they are positioned separately, and the inner surfaces must be aligned, so that the corner deflectors can be raised and lowered independently without affecting the airflow inlet section and the airflow outlet section. Airflow inlet sectio...

Abstract

The invention relates to the field of aerodynamics, and discloses an automobile wind tunnel first corner section test device which comprises a steel flow channel collection port, a corner flow deflector and a flow deflector lifting device. The steel runner collecting port comprises an airflow inlet section and an airflow outlet section, and the corner flow deflector is arranged between the airflowinlet section and the airflow outlet section. The flow deflector lifting device comprises a flow deflector lifting bracket, a flow deflector lifting truss and a flow deflector guide device. The flowdeflector lifting truss is connected to the top of the flow deflector lifting bracket. The flow deflector lifting bracket is arranged on the peripheral side of the steel runner collecting opening. Theflow deflector lifting truss is movably connected to the top of the corner flow deflector. Only the first corner section flow deflector is lifted through the flow deflector lifting device, the steelflow channel body of the first corner section does not need to be moved, the needed lifting load is small, the flow deflector lifting device does not adopt a balance weight adding mode, the needed moving space is small, and the implementation difficulty and economy are good.

Description

technical field [0001] The invention relates to the field of aerodynamics, in particular to a test device for the first corner section of an automobile wind tunnel. Background technique [0002] The wind tunnel is a large-scale test facility used to study aerodynamics. It is mainly used to measure the wind resistance of the car. It can also study the effects of airflow bypassing the body, such as lift and downforce. It can also simulate different climate environments. , such as high temperature, low temperature, rainfall or snowfall, etc. [0003] The first corner section in the steel runner of an automobile wind tunnel is a key part of the steel runner, which includes a corner guideway fixing part and a deflector, the inlet part is connected to the collection port, and the outlet is connected to the transition section behind. During the automobile wind tunnel test, the car needs to enter and exit the test chamber, and the passage setting for entering and exiting the test c...
