Embodiment Construction

[0016] Further features of the invention will emerge from the following description with reference to the accompanying drawings, which are intended only as non-limiting examples.

[0017] It mainly proposes the cooperation mode of each key equipment of the wind tunnel, and arranges the key equipment of the wind tunnel reasonably. The main feature is that all the key equipment of the wind tunnel test, including the ground effect simulation system of the moving belt, the six-component force mechanical balance system, the vehicle body support device and the car model, are all installed on the base of the test section, which is a large rotatable The mechanical rotation mechanism can ensure the completion of the wind tunnel test on the yaw of the car model in the wind tunnel. The balance of the wind tunnel is directly installed on the base of the wind tunnel, which can ensure that a section of the mechanical balance is in contact with the ground to complete the fixation of the bala...

Abstract

The invention relates to an automobile wind tunnel test system for matching with moving belt ground effect, which is a structure of a simple model supporting and force measuring device suitable for abroad band moving belt ground effect simulation system, in particular to a wind tunnel equipment layout scheme of a simple wind tunnel balance, a broad band type moving floor board and a wind tunnel model or real automobile support, which guides and completes the design, the manufacture and the installation of wind tunnel equipment using the automobile wind tunnel test system and can complete an automobile wind tunnel test under the condition. The automobile wind tunnel test system lays out the moving belt ground effect simulation system (1) and the wind tunnel balance (3) on the lower part ofthe wind tunnel test section of an automobile, wherein the moving belt ground effect simulation system (1) is arranged below the tested automobile (4), and the wind tunnel balance (3) is connected with the tested automobile (4) through an automobile body supporting device (2).

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...
