Assesment of The EMU and Track Condition Monitoring Results from Chosen Track Sections During Normal Operation

Rafał Melnik, Andrzej Chudzikiewicz

Abstract


The paper contains analyses of the recorded acceleration signals obtained from the prototype of the rail vehicle suspension condition and track condition monitoring system. Primary and secondary suspension condition is assessed upon acceleration signals registered in measuring points located on bogie frames and vehicle body. The prototype is installed on electric multiple unit (EMU). Data was registered during normal operation of the vehicle on selected sections of one of the main rail lines in Poland. The aim of the analyses is to examine relation between proposed statistical parameters and normative parameters included in rail standards (UIC 518, EN 14363). The analyses were performed generally in cases of exceeding normative parameters values.
The problem of assessment of results as well as monitoring system prototype are parts of research project 'MONIT - MONITORING OF TECHNICAL STATE OF CONSTRUCTION AND EVALUATION OF ITS LIFESPAN'
