Abstract

The invention relates to hydromechanical device, in particular to a wind tunnel used for comprehensive climatic environment tests and aerodynamic tests of railway vehicles. The wind tunnel comprises a tunnel body. The tunnel body is an annular flow channel. A ventilation system used for generating air flow is arranged in the tunnel body. The tunnel body is further provided with an environmental simulation system and an aerodynamic simulation system. The environmental simulation system is used for controlling the weather conditions in the tunnel body. The aerodynamic simulation system is used for enabling the air flow to form a pneumatic flow field. By the adoption of the wind tunnel, the climatic environment tests of the whole real railway vehicle can be carried out, and the aerodynamic tests of a scale model of the railway vehicle can also be carried out. On the basis that the demands for the railway vehicle tests can be met, the wind tunnel can also be used for the related environment tests and the related aerodynamic tests in the fields such as the aerospace field, the automobile field and the construction field.

Description

Technical field [0001] The invention relates to fluid mechanics equipment, in particular to a wind tunnel used for comprehensive climate environment test and aerodynamic test of rail vehicles. Background technique [0002] At present, adaptability to the climate environment is the main consideration in the design of rail transit vehicles, and the ability to test and test for different climate environments is an important guarantee for the design, optimization, and manufacturing of rail vehicles. High and low temperature, rain, snow, and ice accumulation have a major impact on the safe and efficient operation of rail vehicles. In the design process of rail vehicles, effective measures need to be taken to eliminate the adverse effects of severe weather conditions on the operation of the vehicles to the greatest extent, so that they can fully operate in all weather. At present, there is no wind tunnel for comprehensive climate and environmental testing of rail vehicles in China. [...
