Optimization Design and Analysis of Aerodynamic Performance of New Energy Vehicles in Vehicle Engineering
Abstract
In the context of global energy transition and environmental protection, aerodynamic performance optimization for new energy
vehicles (NEVs) has become a critical technological pathway to enhance driving range and ride comfort. Confronting the unique structural
and performance requirements of NEVs, traditional aerodynamic optimization methods demonstrate limitations, necessitating innovative
strategies. Through systematic analysis of aerodynamic resistance composition and influencing mechanisms, combined with computational
fluid dynamics simulations and wind tunnel experiments, this study investigates optimization approaches including whole-vehicle shape
design, underbody flow field management, and active aerodynamic control systems. The research establishes an aerodynamic performance
evaluation framework tailored for NEVs. Results indicate that comprehensive aerodynamic optimization strategies can effectively reduce
drag coefficients by 15%-25%, significantly improving driving range. These findings provide theoretical foundations and practical guidance for NEV design.
