ANALIZA COMPARATIVĂ A REZULTATELOR PROGRAMELOR DE SIMULARE A ŞERPUIRII CADRULUI ŞINE-TRAVERSE CWERRI, SCFJ ŞI CWR-BUCKLE

Abstract

In this paper is presented a comparison of the numerical experiment results which were achieved with SCFJ, CWERRI and CWR-BUCKLE softwares. The two analyses of CWR stability software, one developed at TU Delft (Holland) for ERRI – called initialy CWERRI, and nowadays LONGSTAB – and the other, developed at Foster&Miller company, for Federal Rail Administration of United States of America (FRA) – software called CWR-BUCKLE [6], [11] are mentioned in the new Leaflet UIC 720 [10], for the introduction of concepts and criteria for the CWR buckling safety assessment. In this context, at the Civil Engineering Faculty from Braşov was developed a software for the simulation of the CWR track buckling, in presence of thermal and vehicle loads, model called SCFJ [2], [3].
