Abstract

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.
