For high-speed moving objects in the air, the air resistance and turbulence generated by the airflow around the moving object will directly affect the movement trajectory and speed. The shape of the hood can effectively adjust the flow direction of the air relative to the car's movement and the obstruction force generated on the car, reducing the impact of the airflow on the car.

Pracical problems
In order to better fit during assembly, it is necessary to perform a 3D scan of the product, compare the 3D digital model with the original data, and test whether the product specifications are qualified. The surface of the hood is incomplete, with many holes and complex surfaces, making it difficult to accurately measure the surface of the hood using traditional measurement methods.
Solutions
In order to effectively control the accuracy of data, Hualang 3D engineers proposed to use the handheld 3D scanner HOLON B71 to obtain the 3D data of the engine hood, import the comparative analysis software for data comparison, detect whether the product is qualified, improve the detection efficiency, and ensure the product qualification rate.
