Description

technical field

[0001] The invention relates to an arrangement plan of an automobile wind tunnel test equipment for a ground effect simulation system equipped with a wide moving band exceeding the width of the vehicle. This test layout scheme mainly includes the positional relationship between the moving belt ground effect simulation system and the balance system, and the support method for the vehicle model test. Background technique

[0002] Automobile wind tunnel is the main test equipment for automobile aerodynamic test. Car wind tunnels are generally equipped with moving belt ground effect simulation systems. There are currently two ground effect simulation systems, broadband mobile ground effect and narrowband ground effect simulation systems. For the wide-band ground effect simulation system, the test is generally carried out in the form of a top support model located at the top of the wind tunnel. The top support is finally connected to the balance through a conne...
