Abstract：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.
