Title: COMPARATIVE STRENGTH ANALYSIS OF THE RAILWAY CANTILEVER
Keywords: cantilever, FEM analysis, test
Abstract: The paper is dedicated to comparative analysis of the results of the static strength calculation of the cantilever and the tests that have been carried out. Strength calculations have been made using the Finite Elements Method in the Department of Railway Engineering at the Technical University – Sofia. Three different types of Finite Elements (solid, shell and beam) have been used for calculations. The tests of the cantilever have been carried out in the Testing laboratory of Department of Railway Engineering. It was found that the stress results are very similar, especially in the areas with maximal values. This proves that a suitable calculation model with a relatively small number of finite elements has been developed. This allows solving a wide range of problems concerning the improvement of the cantilever with similar construction.
