| 摘 要： | 确定主要的车身尺寸,草绘车身造型图,使用UG软件完成车身模型,对车身曲面进行光顺性分析,保证曲面的光顺性。用GAMBIT进行网格划分,对车身、地板等要求网格密度高的部分使用手动划分网格,远离车身的部位采用自动划分方法。使用FLUENT软件进行分析,通过对气动阻力和气动升力等动力性指标的不断优化,为车身的选型及造型提供依据。用数值模拟结果修改车身造型,得到比较满意的结果,有利于较早地避免产品缺陷,提高燃油的经济性能,对于新型车抢占市场极其重要。

| Abstract: | In order to ensure the smoothness of the curve,dimensions for main body are determined,body styling is sketched and model is built with UG software as well as body curve is analyzed for smoothness.Then high density meshes for body and floor are divided manually and others far from the body are divided automatically by GAMBIT.After analyzing with FLUENT,body lectotype and styling are decided by the optimizing dynamics properties of aero resistance and lift etc.Afterwards,successive modification on body styli... |
