With the advent of powerful computers simulation of complex mechanical systems has become a real possibility. A computer model of a railway vehicle can be constructed and run on typical or measured track in a virtual environment, and a wide range of possible designs or parameter changes can be investigated. Outputs from the model can be set up to provide accurate predictions of the dynamic behaviour of the vehicle and its interaction with the track. Optimisation of suspension or other parts of the system can be carried out, and levels of forces and accelerations can be checked against standards to ensure safe operation.
