摘　　要：本文详细介绍了某新能源轿车在空气动力学性能开发以及续驶里程能力提升方面所采取的策略与实施过程。项目初期明确了通过减小车辆行驶过程中的风阻系数来达到提高续驶里程的目标。本研究采用CATIA和SolidWorks软件进行三维建模,并利用STAR-CCM+对设计方案进行了仿真模拟分析。项目着重关注车头A柱倾角部分的设计优化,该区域对于整车外形轮廓有着重要影响,直接关系到能否有效降低空气阻力。通过对不同设计方案下A柱角度的变化进行深入研究,并对优化方案进行了减小阻力的原理分析,最终通过模拟风洞试验进行检验,达成了项目初期既定的减小风阻的目标。This paper provides a detailed introduction to strategies and implementation processes for enhancing the aerodynamic performance and driving range of a new energy sedan.The project aimed to improve the driv‐ing range by reducing the drag coefficient during vehicle operation.CATIA and SolidWorks were used for 3D modeling,while STAR-CCM+facilitated simulation and analysis.The study focused on optimizing the A-pillar inclination,as this area significantly affects the vehicle's overall profile and its aerodynamic drag reduction capability.Various A-pillar angles were analyzed to explore the principles of drag reduction optimization.Simu‐lated wind tunnel tests validated the findings,achieving the goal of reducing aerodynamic drag as defined at the project's outset.
