Pombo, (Editor), "Proceedings of the Third International Conference on Railway Technology: Research, Development and Maintenance", Civil-Comp Press, Stirlingshire, UK, Paper 220, 2016. doi:10.4203/ccp.110.220

Keywords: high speed train, optimization method, GA-GRNN, kriging model, genetic algorithms.

Summary

In this paper, different optimization methods are proposed which are the combination of different surrogate models and algorithms. The simplified CRH380A high speed train with three carriages is chosen as the model, and the optimization objectives include the aerodynamic drag of the whole train and the aerodynamic lift of the trailing car. Through comparing differences of the aerodynamic drag and lift between the optimized high speed train and the prototype train, the advantages and disadvantages of different optimization methods are assessed, and the simple, efficient, convenient and accurate optimization method is determined.
