The focus of the present research project is on the integration of a detailed finite element model to accurately simulate the complex material behavior of elastomer bearings and thus significantly improve the prediction accuracy of multi-body simulations (MBS). For this purpose, a material model is developed, which is implemented into the finite element method (FEM) and integrated into the MBS through a solver coupling to ensure computational efficiency. This is achieved through a feedback coupling between FEM and MBS, while ensuring efficient numerical implementation. The simulation results provide necessary material and geometry parameters for the optimization of elastomer components. The summarized simulation process allows for the realistic representation of loads from MBS to simulate the overall system behavior, taking into account the macroscopic behavior of the elastomer components, which is composed of the complex material behavior and the real component geometry.
