Study of transitional phenomena in rail vehicle dynamics in relation to the reliability and operational state of the continuous welded rail track in terms of rail joints

This paper presents the results of experimental and numerical studies on reliability monitoring issues railway infrastructure in terms safety operation. The state knowledge concerning methods assessing track condition, particular rail joints used continuous welded lines is described. Experimental transition zones studies/tests vehicle-track model are outlined. It demonstrated, basing analyses results, that not only should be diagnosed during their acceptance, but also proven currently methodology for testing applied acceptance contact fully correct leads to misinterpretation measurement results. Moreover, simulation tests presented this confirm possibility diagnosing condition by any vehicle passing over such a equipped with suitable system.
