中文摘要:
      目的 研究大溜背造型对SUV整体车身造型及气动特性的影响,分析SUV融入大溜背造型后的车身造型风格及气动特性变化的规律。方法 在明确认识SUV大溜背造型特征的基础上,利用汽车造型视觉特征、语义特征对SUV大溜背造型进行定性分析;运用CFD数值模拟计算大溜背造型的气动阻力系数,并研究随着大溜背造型倾斜角度的改变SUV气动阻力变化的规律。结论 SUV大溜背造型使SUV车身设计趋于一体化,在造型风格上更加强调运动、流畅、一体化;大溜背造型特征能够有效地降低SUV气动阻力;随着大溜背造型倾斜角度的增大,SUV的气动阻力系数也呈不断降低的趋势。
英文摘要:
      It aims to research the effects of SUV Fastback modeling on automotive modeling design and automotive aerodynamic characteristics. It analyzes SUV modeling style and variational rule of aerodynamic characteristics after it got blended into SUV Fastback modeling. On the basis of a clear understanding of the modeling feature of SUV Fastback, the methods of visual features and semantic features of automobile modeling are used by qualitative analysis for the modeling feature of SUV Fastback. By using CFD numerical simulation to calculate the aerodynamic drag coefficient, and the variational rule of aerodynamic drag of SUV with the tilt angle of SUV Fastback modeling is stuided. SUV Fastback modeling turned the SUV body design tends to integration, and more emphasis on the sense of movement, fluency and integration in the design; SUV Fastback modeling can reduce the aerodynamic drag effectively. The aerodynamic drag coefficient of SUV decreases with the increase of the tilt angle of SUV Fastback modeling.
