ALGORITM PENTRU STABILIREA RESTRICŢIEI DE VITEZĂ ÎN FUNCŢIE DE PROBABILITATEA DE PIERDERE A STABILITĂŢII CADRULUI ŞINE-TRAVERSE

Abstract

This paper presents an algorithm for appraisal of temporary train speed limits using a probabilistic simulation of the buckling of the continuous welded rail (CWR) track. The temporary train speed limits disturb normal passenger and freight traffic and determine losses due to the decrease of circulation capacity on the railway. The accurate estimation of the allowable temperature limit and of the corresponding safe speed limit on a given railway sector introduced on the basis of the estimation of the risk of temperature buckling is an imperious necessity. Because of the great variability of main parameters which govern the stability of the CWR track, these temporary train
