Due to the short streamline nose, the aerodynamic performance of Shanghai maglev train is not very good. In this paper, several streamline shapes were designed for domestic maglev train according to the given section and requirements supplied by domestic rolling stock works. By using the three-dimensional compressible N-S equations and turbulence model, aerodynamic performances of all schemes were analyzed, and then the streamline shapes were optimized based on the calculation results. In so doing, the best streamline shape with good aerodynamic performance and good appearance were obtained. Because of the narrowest horizontal contour line and the smallest curvature of vertical contour line, the aerodynamic drag force and train passing pressure pulse of the third scheme are the least among the final three selected schemes, so it is the best. The results show that this streamline shape designed for domestic maglev train is better than Shanghai maglev train (TR08) in aerodynamic performance, and the aerodynamic drag force of domestic maglev train is 33.84KN at the speed of 4300 km/h, while TR08 is 54.07KN; at the same time, the train passing pressure pulse of domestic maglev train is 2913Pa, while TR08 is 3827Pa.
