Abstract
Deterioration of the track geometry of ballasted tracks is unavoidable. In order to foresee the deterioration of the track, the phenomena have to be understood and described in an engineering way. Through the years a lot of research has been carried out and a lot of different models have been formulated. This paper contains the results of the analysis of the main causes and factors influencing the deterioration of the track. The literature survey resulted in description of 11 models for track geometry deterioration. The aims of this paper are to present a 'state of the art' overview of existing track deterioration models and their properties, to classify the models, to make a comparative analysis of existing models, and to analyze possibilities of implementation of the models. Criteria for the evaluation of the models are defined. .
Kod koloseka u zastoru, propadanje geometrije je neizbežna pojava. Za uspešno predviđanje propadanja geometrije koloseka, neophodno je razumevanje kompleksnog mehanizma propadanja i opisivanje ovog mehanizma sa inženjerskim pristupom. Do sada su u svetu sprovedena mnogobrojna istraživanja na temu otkrivanja mehanizma propadanja i definisano je više različitih modela propadanja. U ovom radu su identifikovani uzroci propadanja, kao i svi parametri koju utiču na propadanje vertikalne geometrije koloseka. Dat je pregled jedanaest postojećih modela propadanja. Izvršene su klasifikacija i uporedna analiza postojećih modela. Definisani su kriterijumi za ocenu modela i analizirane su mogućnosti primene postojećih modela.
