Pombo, (Editor), "Proceedings of the Third International Conference on Railway Technology: Research, Development and Maintenance", Civil-Comp Press, Stirlingshire, UK, Paper 61, 2016. doi:10.4203/ccp.110.61

Keywords: parameteric-driven, resistance, multi-objective optimization, high speed, electric multiple unit, EMU.

Summary

Reducing the running resistance is the effective way to achieve high operational speed and energy saving for a high-speed electric multiple unit (EMU). This paper establishes an automatic calculation process for parameteric-driven aerodynamic performance optimization of a new EMU head-type. Based on a multi-objective genetic algorithm NSGA-II, a correlation analysis is performed on three key design variables including nose tip height, expansion amount of control points on the cowcatcher and the inclination angle of a bogie region baffle. Then the better aerodynamic shapes of the head are proposed. The research method for aerodynamic design provides a scientific, rigorous optimization design method, and also helps to enhance the level of EMU designs.
