中文摘要
      分体式造型是汽车外形设计的全新领域,在造型方面具有突破性的意义,但突出的问题之一风阻往往比普通汽车更高,因此如何做到低阻化是一个新的课题。本文以A级车为参考车型级别,建立分体式低风阻基本造型,并考虑了人机空间等基本实用性,保证整车在工程上的有一定合理性。之后通过造型不断细化与空气动力学仿真迭代方法,最终获得了风格鲜明的分体式造型,并使其CD=0.2249,达到了预期目标,具有应用与推广价值。
英文摘要
      Split-body styling creates a new field of automotive exterior design which is different from uni-body styling, which has breakthrough meaning as for design, however the air drag will come up to be a new problem. Based on A segment vehicle as reference, it built split-body low-drag basic form, which was considered in the aspect of ergonomics so as to insure the engineering rationality. It started vehicle design with verified basic form. It transformed basic form into real car while keeping the form low-drag by adding details while taking aerodynamic simulation. Eventually, it found design methods related to both design and aerodynamics and obtained one low-drag split-body design proposal, CD of which is 0.2249.
