Zum Einfluss der Flexibilitaet der Fahrzeugstruktur auf das Fahrverhalten von Gueterwagen

摘要

Within a research project at KTH simulation models of freight wagons were established. During investigations it turned out that the flexible properties of the underframe cannot be neglected in the models. Therefore a finite element model of an underframe of a two-axle freight wagon was built up. The most important eigenmodes are incorporated into a multibody model of the freight wagon. Comparisons with measurements are presented. In almost all cases the results for the models with structural flexibility coincide better with measurement results than for the model without flexible modes. Further on results of some parameter studies are presented.
