We present a computational approach to driveline system simulations that aim to better capture how major system deformation modes vary and interact during operation. A prototype of a downsized front-wheel- drive powertrain was run in a physical rig-test and a nonlinear driveline torsional resonance response could be identified. A large-scale powertrain computational model that combines details of finite element component and multibody system design models was developed and used to simulate the rig-test response. The torsional response was calibrated using one subset of measured data and a complementing subset was used for validation. Simulation results show good qualitative agreement with measured responses. A minor parameter study shows how parameter settings of selected components influence the system normal modes.
