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 a test device for the first corner section of an automobile wind tunnel, comprising: a steel runner collection port, a corner deflector, and a deflector lifting device; the steel runner collection port includes an airflow inlet section , the air outlet section, the corner deflector is set between the air inlet section and the air outlet section; the deflector lifting device includes the deflector lifting bracket, the deflector lifting truss, the deflector guide device, the deflector lifting truss Connected to the top of the deflector lifting bracket, the deflector lifting bracket is set on the side of the steel runner collection port, the deflector lifting truss is movably connected to the top of the corner deflector, through the deflector lifting device only the first corner section The deflector is lifted, and the main body of the steel runner in the first corner section does not need to be moved, and the required lifting load is relatively small. The lifting device of the deflector does not adopt the mode of increasing the counterweight, and the required moving space is also small, which is difficult to realize. The economy is better.

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...
