M. Suzuki, M. Satou, T. Ogawa, N. Okura, "Shape Optimization of High-Speed Train with Multiple Aerodynamic Properties", in J. Pombo, (Editor), "Proceedings of the Second International Conference on Railway Technology: Research, Development and Maintenance", Civil-Comp Press, Stirlingshire, UK, Paper 26, 2014. doi:10.4203/ccp.104.26

Keywords: high-speed train, shape optimization, multi-objective optimization, aerodynamic property, evolutionary algorithm, computational flow simulation.

Summary

This paper describes a shape optimization study of a high-speed train nose, with multiple aerodynamic properties. The technique is mainly composed of a multiobjective evolutionary algorithm, a shape parameterization technique, and steady and unsteady flow simulations using message passing interface. Three aerodynamic properties are adopted as objective functions: i) aerodynamic drag, ii) pressure variation around the vehicle, and iii) aerodynamic yawing fluctuation acting on the last car in a tunnel section. After the evolutionary calculation of 10th generation with 32 individuals, physically reasonable Pareto solutions are successfully obtained.
