The present paper describes the CAE-based approach for the analysis of dynamics of a coupled model of a flexible railway bridge and a train. The approach is implemented in Universal Mechanism software. The railway bridge is considered to be a flexible multi-body system. The dynamics of flexible bodies are simulated using data imported from finite element analysis software. An application of the approach to the investigation of dynamics of a railway vehicle and a bridge involves taking into account the flexibility of the bridge. Comparison of flexible deflections and stresses for the full and reduced FE-models are presented. The simulation results of flexible deflections and stresses are contrasted with experiment data.
