In the process of designing the aerodynamic kit for FSAE racing cars, there is a lot of repetitive work and low efficiency in optimizing parameters such as the angle of attack, chord length, and wing gap size. The optimization of these parameters is difficult to achieve through theoretical analysis and heavily relies on simulation results and design experience. Due to the short design cycle of racing cars, it is challenging to achieve the optimal solution. By establishing a parametric model in CAD software and integrating it with CFD software, the model parameters are automatically modified, imported into the CFD software for automatic simulation, and the simulation results are automatically analyzed using statistical methods. Based on the results, the model parameters are optimized within the allowable range of rules. After multiple iterations, the parameters are fully automatically optimized, achieving a higher negative lift coefficient.
