Revving Up Innovation: Empowering Automotive Industry Through Advanced Manufacturing Technologies for Vehicle Aerodynamics

Résumé fourni par la source

This study explores the application of advanced manufacturing techniques in the development and testing of vehicle aerodynamics, emphasizing the rapid production and high precision of complicated components. Traditionally, creating prototypes for aerodynamic testing involved significant time and resources, leading to prolonged lead times and high costs. However, advanced manufacturing technologies such as 3D printing, CNC machining, and composite manufacturing have revolutionized this process, allowing for the swift creation of complex wind tunnel models and scale prototypes that accurately represent vehicle geometry. This paper presents an experiment aimed at constructing a low-cost, small-scale race car model for aerodynamic testing through 3D printing. The project concluded in the design and development of a race car, accompanied by a 3D-printed prototype, with the design currently pending patent approval. Key components of the design include a front wing end plate, a Venturi Channel, replaceable Gurney flaps, and a variable angle of attack rear wing, each contributing to optimized aerodynamic performance in high-speed racing scenarios. Additionally, the front wing, highlighted in red in the design, is pivotal in generating downward pressure and elevating oncoming airflow to reduce wheel drag. This research demonstrates that advanced manufacturing can significantly streamline the process of creating aerodynamically efficient vehicle prototypes, reducing both lead time and cost. The integration of 3D printing in producing these models demonstrates the potential for rapid iteration and refinement, facilitating more efficient and costeffective aerodynamic testing. The findings underscore the importance of advanced manufacturing in modern automotive engineering, offering valuable insights for future developments in race car design and aerodynamic optimization.
