The presented article deals with the application of Reverse Engineering and Rapid Prototyping processes in the development process in the automotive industry. In our case, we will focus on the design of the exterior rear view mirror. We obtained the information about the shape and as well as the data used to model the part in a virtual CAD computer environment by scanning it with a Leica laser scanner. The obtained point cloud was imported into CATIA V5 software, which is often used in the automotive industry. In the CATIA software modules, section curves were translated into cloud points. Based on these curves, free shaped surfaces of the mirror body and its holder on the car door were created. After creating the mirror body-mirror mount assembly, print data of these parts were generated for production by Rapid Prototyping technology. The printing method based on ABS material using the FDM (Fused Deposition Modeling) method was chosen.

The paper deals with the possibilities of reducing aerodynamic drag and modifying airflow in the rear of a hatchback vehicle. This body type is characterised by the formation of turbulent flow behind the vehicle, which has a significant effect on the fouling of the tailgate, including the window. By modifying the geometry of components such as the roof spoiler and additional aerodynamic finlets on the sides of the rear window, the airflow is optimised to reduce aerodynamic drag and thus fuel consumption. Three spoiler designs are proposed, one of which is processed to prototype quality using CAD tools. The body of the vehicle with this design is subjected to CFD analysis and evaluated in terms of the given criteria. The results of the simulations are compared with a model of a production vehicle and a sports version vehicle to assess the effect of the geometry on the flow parameters.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
