Taking the aerodynamic performance as the guide to extract the shape features of Shinkansen trains, this paper aims to establish a topological shape design method with synergy of shape and performance, and improve the quality of the shape design of high-speed trains in our country. The eye movement experiments are used to conduct regional induction and analysis of the shape according to the Shinkansen train shape database.to obtain the four important areas of nose end, front face, shoulder and running gear of the head shape; the type linearity and change trend of each regional model for 16 models since the operation of Shinkansen according to four development stages are summarized; combined with the corresponding relationship between the characteristics and aerodynamic performance of each region of the head shape, a shape collaborative design method for Chinese train design is established.. Through the reasonable application and adjustment of the characteristics such as the curve turning of the train shoulder and running gear, the flat and wide shape of the nose end, and the cab bulge of the front face, the design quality of the train shape can be improved while giving consideration to the aerodynamic performance.
