文章以高速列车车头造型为研究对象,探究不同截面框架生成的设计方案对风阻系数的影响差异,使用参数化设计方法改变车头横截面形状,逐步建立完整的列车数据模型。采用模拟流体分析的方式,证明横截面参数均匀化的车头形状的空气阻力系数最小,论证了参数化设计方法在实际应用中的可行性,以期为列车外观设计提供有效的参考数据和有益的优化经验。

The article takes the shape of the front end of high-speed trains as the research object,explores the differences in the influence of design schemes generated by different cross-sectional frameworks on the wind resistance coefficient,and uses parametric design methods to change the cross-sectional shape of the front end,gradually establishing a complete train data model.By using simulation fluid analysis,it is demonstrated that the air resistance coefficient of the uniform cross-section parameter of the front shape of the train is the smallest,and the feasibility of the parameterized design method in practical application is demonstrated,in order to provide effective reference data and beneficial optimization experience for the appearance design of the train.
