The proposed large research equipment opens the possibility for experimental investigation of complex technical systems under multi-dimensional dynamic loading and excitation. Validating of virtual models of dynamic behaviour of rotating and oscillating machines’ components enables to reliably predict their multi-dimensional vibrations. So far, the corresponding necessary excitation could be applied and their effects could be analysed only separately. The combined loads usual in complex technical products couldn’t be experimentally simulated with common equipment in sufficiently realistic conditions. Hence, the model validation is usually performed either using one-dimensional test rigs for specific subsystems and their components or with the whole machine. Only partially validated models come into being in the first case, because the spatial (nonlinear) superposition effects cannot be sufficiently reproduced is such experiments. Consequently, the transfer of such models and their applicability for predicting of multi-dimensional interactions in a complex system are at least questionable. In the second case, it is extremely difficult to separate effects within certain subsystems from the phenomena evoked by the influences of the machine as a whole.Acquisition of the proposed equipment enables to rise up at KIT the unique research and validation environment for development of complex drive systems taking into account such aspect and trends as lightweight construction, energy and economic efficiency, reliability. The suggested equipment will be integrated in the existing testing facilities which enables to achieve synergetic effects reducing the costs of the proposal. Cooperation between different domains of engineering (design, validation, modelling in mechanical and electrical engineering) sciences will be significantly strengthened due to the realization of the proposed large research equipment.
