K. Zboinski, P. Woznica, "Optimization of Railway Transition Curves with regard to the Wheel/Rail Wear", in J. Pombo, (Editor), "Proceedings of the Second International Conference on Railway Technology: Research, Development and Maintenance", Civil-Comp Press, Stirlingshire, UK, Paper 206, 2014. doi:10.4203/ccp.104.206

Keywords: railway transition curves, railway vehicle dynamical model, computer simulation, optimisation.

Summary

This paper presents the method and results of the optimization of railway transition curves. The software used is a combination of the authors' own railway vehicle dynamics simulation software and a procedure from the optimization library. Corresponding quality functions concern measures of wear in the wheel/rail contact. The decision variables are polynomial coefficients defining transition curve shape. Sixth, Eighth and Tenth degree polynomials are considered. Results of the optimization are compared. Reference to the influence of the order of the polynomial terms and the geometrical demands on the results is made.
