摘要：针对Honda节能竞技的特点，大赛对赛车车身提出了低风阻、轻量化的要求。文中综合考虑车身造型基础和美学原则，建立了第三届湖南大学潇湘之鹰车队赛车UG简化模型，并利用CFD流体计算方法对赛车进行了外流场数值模拟。根据风阻系数、车身表面压力、车身表面速度矢量等计算结果，对车身外形进行定量分析和评价，为下一届赛车的设计提供设计经验和理论基础。
　　
关键词：CFD分析，外流场，风阻，车身外形

Abstract:Aimed at the characteristics of Honda Energe-saving Match, the design of racing car body should meet the requirement of low drag and utralight.In this paper, comprehensively considering basis of racing car modeling and principles of art,the racing car model of “XiaoXiang Zhi Ying ”of Hunan University is instituted.Next we use CFD Method to make the external airflow field analysis. We can obtain some information according to the results of drag coefficient、body surface pressure and body surface velocity vector, The results of quantitative analysis would offer some design experience and theoretical foundation to the car styling for next match.
　　
Keyword: CFD analysis, external airflow field, drag coefficient
