With the ongoing digitalisation of the vehicle development process, virtual design methods play an increasingly important role. Representative load profiles are required for the reliable design and validation of complex elastomeric components such as powertrain mounts in conventional and electrified powertrains which can be determined using multi-body simulation. Due to the complex material properties and the elaborate designs of today's elastomer and hydro-mounts, the virtual representation of these components is a challenge. Within the scope of already published investigations, a novel complex mount modelling method for the improved virtual determination of operating load data was presented. The improved representation of the physical properties of elastomeric and hydro-mounts which occur under high dynamic spatial excitations is the focus of the methodology. The virtual mount model has been considered and evaluated in previous investigations using fixed excitation states. This means that only the deformations determined on the test rig serve as input values for the comparison of the model quality between measured and simulated loads. The main focus of the investigations presented here is the evaluation of the functionality and simulation quality of the new modelling approach in a freely oscillating mechanical system. For this purpose, the model represented in Matlab/Simulink will be implemented in Adams/Car using general equations of state. The state equations are exported from the Matlab/Simulink environment as C code. In the first step, a functionality plausibility check of the exported model between Matlab/Simulink and Adams/Car is performed using a virtual elastomer mount test rig. The model is then used in a complex track simulation. Based on the test results, model adjustments are made and lastly the simulation quality of the modelling approach outside the models fitting range is evaluated.
