With the development of automobile technology and highways, the driving speed of automobiles is increasing day by day, and the aerodynamic resistance of the vehicles interacting with air during driving is also becoming more and more significant. It affects the economy, dynamics and stability of automobiles to a large extent. Sex. In recent years, the numerical simulation of automotive aerodynamics has developed rapidly. By optimizing the aerodynamic performance, reducing the air resistance coefficient and improving the fuel economy, considerable economic benefits can be generated. The body of the van is higher than the cab. When the van is in high speed operation, when the airflow above the cab hits the upper part of the front of the closed compartment, a large peeling occurs from the front edge of the ceiling, and the air resistance coefficient The value increases as a result. If a guide device is installed on the top of the cab, a streamlined transition between the cab and the carriage is used to guide the airflow passing through the upper part of the cab to “engage†with the upper surface of the carriage so that the airflow is along the top of the closed box. The flow of the cover surface is very close, which reduces the coefficient of air resistance. Therefore, it is more necessary to install the shroud in the van.
The use of a shroud contributes to the development of green freight, and proposes new ideas and solutions for solving the problems of energy saving and emission reduction in the freight industry.
At present, there are a number of manufacturers that specialize in producing shrouds. Green freight is moving forward.
