Riassunto analitico
This thesis document recounts the work carried out during the curricular internship at Visa Cash App Racing Bulls Formula One team within the Design Office at the Faenza Headquarters.
The objective of this project is to thoroughly explore and analyze the kinematics of the Drag Reduction System (DRS) used in Formula 1 cars. The study draws on classical principles of Applied Mechanics, supported by CAD and dynamic simulation tools, with the aim of providing a comprehensive methodology and practical tools to assist engineers and designers during the conceptual phase of DRS kinematic sign-off.
The research is structured into two main phases. The first phase focuses on determining the system's kinematics and statics, ultimately leading to the development of an analytical tool capable of calculating and comparing motion ratios and static forces on the mechanism for any Rear Wing DRS configuration. The second phase involves an in-depth dynamic analysis. This phase includes bench experiments conducted to characterize the pneumatic and hydraulic loads acting on the system. A detailed discussion follows regarding the loads and their integration within the dynamic simulation in the NX Motion environment, aimed at evaluating opening and closing transients. The approach is incremental, consisting of a step-by-step validation process to decouple the effects of each load and ensure a realistic representation of their individual contributions.
Once the bench experiment and dynamic simulation are validated, the acquired knowledge is transferred to the full-scale Rear Wing model, incorporating aerodynamic loads. Validation of the simulation is then carried out by comparing the results with data from a track test conducted during the 2024 F1 Belgian Grand Prix.
Upon completion of this project, designers will have access to a validated methodology capable of predicting DRS opening and closing transient times, thereby aiding the understanding and optimization of design choices.
