This contribution deals with the investigation of an approximately 1/10-scaled model of a metro vehicle car body concerning the low structural eigenmodes. The model has been developed by means of finite element calculations in such a way that the eigenfrequencies of the model lie close together. An experimental modal analysis has been carried out to determine the structural dynamics behavior of the realized model. The achieved results verify the predicted dense lying eigenfrequencies. In addition to that the accomplished experimental modal analysis provides a sophisticated basis to improve the modelling of the investigated structure for control purposes. Such simulations and measurements are done to support design developments and concepts to achieve a higher ride quality for metro vehicles.
