Railway Dynamics and Wheel-Rail Contact. Simulations and Testing for Running Dynamics Behaviour Assessment

The successful design of rail vehicles asks for good understanding of the system, high technical competences and wide experience on the field as well as appropriate and advance simulation models, tools and methods to be used during the different design phases. Figure  53 illustrates the main railway dynamics activities within the whole engineering design process. At the center there are modeling and simulation activities : the simulations are widely used and play a fundamental role on the design, having different roles during the development phases. In concept design, they are used to assess the feasibility and highlight risks and mitigation solutions. During detailed design, simulations apply to optimize the designs and support the...
