Kurzfassung

Railway car bodies for passenger trains in Europe are designed according to EN 12663-1 but the load assumptions contradict the goals of designing light and energyefficient car bodies. Hence a sensitivity analysis is carried out to determine the influence of the load cases of EN 12663-1 on the overall vehicle structure to identify the relevant loads. The load cases of EN 12663-1 are examined for their sensitivity to the system response with the help of design of experiments. As an essential parameter for the design of railway car bodies the weight force is identified. The longitudinal force at the buffer level is described as a dimensioning load if it is applied at the maximum level. However, an operating situation with this load magnitude is not known. Furthermore, load cases are uncovered that are not relevant for future designs due to their redundancy with other load cases. Over-dimensioning can be assumed as a result.
