Design optimization of frontal hatch cover of high speed train was preformed for reduction of aerodynamic load. For this, the shape function was used to model the frontal hatch cover. Then, a total of 15 design points were selected using three design variables: the length of the hatch cover, top-view curvature, and side-view curvature. A three-dimensional flow analysis was performed for each design point. Finally, the optimal shape was derived through optimization, and the aerodynamic load of the optimal shape was compared with that of baseline model. As a result, the length of the frontal hatch increased compared to the baseline model and the aerodynamic load was improved by about 20% from 4,890N to 3,920N through the optimized shape.
