Introduction to the Design of Automotive CWT

The work aims to simulate real natural environment to carry out automotive test by the essential testing tool of automotive climatic wind tunnel. The overall design concept of automotive climatic wind tunnel was introduced briefly and the essential aerodynamic and environment simulation systems were elaborated carefully. Every component of the airline had its unique function and excellent aerodynamic performance could be generated by collaborative design of all components. Design of environment simulation systems ensured the cooling capacity and met the requirements of automotive environment conditions by considering the heat load of wind tunnel equipment and test and the temperature rising and falling rate of wind tunnel. In addition, equipment simulating natural environment such as roads, sunshine, rain and snow were equipped. Different components of CWT had their own functions and could provide excellent aerodynamic and thermodynamic ability. Through comprehensive design, CWT can simulate natural environment properly for automotive test.
