摘　　要：以空气动力学仿真分析为前期开发工具,以气坝、发动机机舱底护板为研究对象,针对某SUV车型的空气动力学附件进行了整车气动性能分析与优化,通过实车风洞试验验证了气动附件良好的降阻效果。通过整车散热性能试验、阻力滑行试验及高速操纵稳定性试验可知,增加以上气动附件,能够在满足整车散热性能的同时降低油耗,提高车辆的高速操稳性能。In this paper, we analyze and optimize vehicle pneumatic performance of aerodynamics accessories of a SUV, with aerodynamics simulation analysis as the early development tools, air dam and bottom plate as the object of study. Vehicle wind tunnel test proves that the pneumatic accessories have good drag reduction effect. Then, it is known through vehicle heat dissipation performance test, resistance coasting test and high speed handling stability test that,adding the pneumatic accessories can not only reduce fuel consumption and improve handling stability of the vehicle in high speed driving, but also meet the heat dissipation performance.
