The project content was a feasibility study to validate the concept of a car body for the low-floor local passenger train ‘LF Commuter NPZ’.
The construction of the car bodies was carried out using large aluminum profiles, which serve as the basis for the conventional welded construction used here.
FE shell/beam modeling was performed to determine the necessary stiffnesses and strengths of the car bodies. The stresses under service load, under the maximum loads at buffer pressure and the natural frequencies of the car body were determined.
The two figures in the reference sheet show the half-model of the end car used and the calculated deflections under the dead weight of the operational car body (i.e. including the interior fittings, all add-on parts and the electrical equipment attached to the roof).
