Experimental and FEM analysis for biaxial static and fatigue behaviour of the aluminium structures of rolling stock’s seats

This paper concerns the numerical and experimental characterization of the static and fatigue strength of an aluminum structure of rolling stock's seats. A series of static and fatigue test on full scale structure has been carried out using a biaxial test machine specifically designed, built and located in the laboratory of A-Technology industry to investigate the static and fatigue strength. The experimental results have been compared with numerical ones showing a very good correlation. The present paper gives an overview of such experimental and finite element method investigations specifying the type of loading used in fatigue tests and in FEM analysis and the main results obtained.
