The Comparison of Dynamic Effects Acting in the Common Crossing and Switch Unit of a Turnout

Abstract

The paper presents an analysis and comparison of selected dynamic parameters in the common crossing and switch unit of a railway turnout. The paper includes a description of the measurement methodology, the report of mathematical methods used to evaluate the measured data and comparison of selected parameters describing dynamic processes in individual parts of the structure. The paper also includes a mathematical analysis of the lesser-known Hilbert Huang transformation, including its practical application. From the presented case study, practical experience and recommendations for the railway line managers, research organizations and possibly for the wider technical public are derived.The paper presents an analysis and comparison of selected dynamic parameters in the common crossing and switch unit of a railway turnout.
