摘　　要：为了降低汽车对于能源的消耗,提出了模拟自然风流型的汽车造型设计思想。为此设计了试验风洞装置,成功模拟风流吹过沙子的沙丘形状,并采用非接触三维扫描获得了数字流型及数据,应用其设计了概念跑车前脸造型,有限元仿真证明它能有较低的风阻系数,表明自然风流型在低阻汽车造型设计有较好的应用前景。The design ideas of car modeling of imitating natural wind flow patterns were proposed for decreasing energy consumption of cars.A test wind tunnel was designed and the sand dune patterns were imitated and digitalized accurately by a non-contacted 3-D scanner.The concept sports car surface was designed by the digital patterns with low resistanceas proved by Ansys-fluent.So the flow pattern of natural wind has better application in the low resistance sports car design in the future.
