对 3种典型轿车车身空气绕流的空气动力特性进行了试验研究 ,通过 1 / 8轿车模型风洞试验 ,获得了流场的形貌并对其作出了解释。重点对车身和扰流板在高速侧风时的空气动力特性进行了研究分析 ,给出了车身与气动力特性之间、气动力特性与汽车性能之间的关系 ,通过改变车身尾部外形 ,改进尾流结构进而改善气动力特性 ,提出了提高操纵稳定性的措施
The aerodynamic characteristics of the three typical car body air around the flow were studied. The shape of the flow field was obtained through the wind tunnel test of 1/8 car model and its explanation was given. The aerodynamic characteristics of bodywork and spoiler during high-speed crosswind are emphatically studied. The relationship between the aerodynamic characteristics and the aerodynamic characteristics of the car body and the performance of the automobile is given. By changing the shape of the tail of the car body, Wake structure and then improve the aerodynamic characteristics, put forward measures to improve handling stability
