摘要
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 。
To evaluate the effects of three typical automobile body's shapes on aerodynamic drag and coefficients to driving stability related three simplified 1/8-scale models were built and tested in wind tunnel. The shapes of flow fields were obtained and explained, especially about the relationships between automobile body's shapes and aerodynamic and performance of automobile. The main aspects of aerodynamic of autobody and its spoiler when the models were blown by high speed cross wind are discussed. Some methods for improving the driving stability are also pointed out.
