Sumario:This thesis investigates the structural behaviour and aerodynamic characteristics of a racing car sidepod under aerodynamic loads to evaluate the potential impact of controlled deformation on performance and airflow management, particularly towards the radiator. A coupled simulation approach was developed, combining Computational Fluid Dynamics (CFD) to capture airflow and pressure distributions with Finite Element Analysis (FEA) to predict structural response. The study explores how different composite laminates and fibre orientations affect sidepod flexibility, stress distribution, and flow response under realistic operating conditions. CFD simulations were employed to quantify aerodynamic forces acting on the sidepod during representative operating scenarios. These forces were subsequently applied in the FEA model to assess deformation patterns, displacement magnitudes, and potential failure points. Results indicate that specific composite laminates can achieve controlled deformation without exceeding structural limits, potentially improving flow management through the sidepod and towards the radiator. The analysis demonstrates that strategic material selection and fibre orientations can enable beneficial aeroelastic coupling whilst maintaining structural integrity. The findings contribute to understanding how sidepod deformation can be exploited to enhance vehicle performance, improve cooling efficiency, and inform the development of higher-performing racing car designs.
