Determination of equivalent loading of turnout frog
Original language description
In the course of a vehicle passing over a turnout, a high dynamical response appears during passing over the turnout frog. The increased loading of this turnout part negatively influences its wear and finally its service life too. The methodology for determination of the equivalent loading of a turnout frog in the course of a vehicle passing has been developed just for the evaluation of the frog loading. A vertical acceleration measured on the wheelset axle box of a vehicle passing over the frog is an input parameter for the calculation of the equivalent loading. Actually the turnouts of several types built in modernized station Ústí nad Orlicí are monitored since 2014 in a cooperation with a turnout producer and one of the train operator with application of the mentioned methodology. The reference vehicle for the evaluation of these turnouts is an electric locomotive of axle load 22 t. The verification of optimized design of some turnouts in terms of loading of their frogs is the purpose of this project.
