N2 - The digital transformation in automotive industry is one of the main challenges in future. Consequently, reliable finite element (FE) models become an important role in early design and concept phase. Due to the seat ride comfort the prediction of the dynamic seat behavior has an immediate effect of the customer acceptance. The application of FE-models enables the evaluation of the structure dynamic behavior in early design phases. Hence the simulation-based prediction plays an important role to meets the Noise-Vibration-Harshness requirements as trade-off between development time, costs and lightweight targets. The purpose of this study is to present the challenges in numerical characterization of the seat structure. The vibration behavior is inflected by manifold sensitive linear and nonlinear parameter which are discussed. The seat system as well as the subsystems seat backrest and seat frame are characterized by means of experimental modal analysis. These measurements are used to validate the FE-models. The main vibration contributor regarding to the full seat system are identified. The results from experiments are implemented in the FE-model to improve the predictive power of simulation results.
