Abstract:

Integrated aerodynamic performance of a luxury sports sedan， including aerodynamic resistance， lift force， and wind noise， was studied and optimized. Taking a clay-rigid material mixed full-scale model and its 1：1 digital model as main research objects， an in-depth， full-scale wind tunnel test and numerical simulation were conduct on shape surface， bottom guard plate， aerodynamic hub and sealing strip of the vehicle. A wind resistance coefficient of 0.269， a greatly optimized driving stability， and wind noise level were obtained. This paper introduces the specific engineering experience and relevant theoretical support obtained in the development process.

Key words:vehicle engineering;aerodynamics;wind tunnel test;computational fluid dynamics;lift coefficient
