Abstract:
In this paper, active aerodynamic wings are investigated using numerical simulation in order to improve vehicle handling performance under high-speed cornering maneuvers. Air foils are selected and analyzed to determine the basic features of aerodynamic wings. Built upon the airfoil analysis, the 3D aerodynamic wing model is developed using a commercial software package, Siemens NX®. Then the virtual aerodynamic wings are assembled with the 3D vehicle model designed also using Siemens NX®. The resulting 3-D geometry model is used for aerodynamic analysis based on numerical simulation using a computational fluid dynamics (CFD) software package, ANSYS FLUENT®. The CFD-based simulation data and the multibody dynamic vehicle model generated CarSim®are combined to study the effects of active aerodynamic wings on handling performance of high-speed vehicles. The systematic numerical simulation method and achieved results may provide design guidance for the development of active aerodynamic wings for high-speed road vehicles.
