In the work presented, a computational tool used for the dynamic simulation of railway vehicle
systems was developed using multibody systems formulations. The model based on the multibody techniques developed by Shabana. ...
[EN] The wheel rail contact problem plays an important role in the simulation methods used to solve railway dynamics problems. As a consequence, many different mathematical models have been developed to calculate wheel ...
