摘要：

This paper established an automatical calculation process for parameteric-driven aerodynamic performance optimization of the new EMU head-type. On the basis of the multi-objective genetic algorithm NSGA-II, optimal design was performed in respect of 6 key design variables including the slenderness ratio of the head type, the longitudinal line of symmetry, the maximum horizontal contour, the horizontal contour of the car bottom, the assisting hatching and the height of the nose. Then the best aerodynamic shapes of the head were selected. The multi-objective optimization design method can support design work of aerodynamic shapes and new head types which adapt to different styles and different technology needs.
