M.A. Boogaard, A.L. Schwab, Z. Li, "High Frequency Response of Frogs using Dynamic Impact Measurements", in J. Pombo, (Editor), "Proceedings of the Second International Conference on Railway Technology: Research, Development and Maintenance", Civil-Comp Press, Stirlingshire, UK, Paper 212, 2014. doi:10.4203/ccp.104.212

Keywords: frog, impact measurement, dynamic response, finite element modeling.

Summary

Models for straight tracks are widespread and well established. More recently the focus has shifted towards more complex geometries, such as insulated joints and frogs. A number of possible models for a frog have already been published, but currently no proper validation in a dynamic sense has been performed. This paper presents the preliminary results of dynamic impact tests on a frog and its components. These measurements are validated with a finite element model. This model is then used to extract important features which influence the dynamic response of a crossing up to 3000 Hz.
