Special Session: RW2016-S13
Advanced Wheel-Rail Contact Models
Session Aims and Scope
Nowadays one of the most challenging problems in the railway field is the accurate modelling of the wheel-rail interaction. Advanced wheel-rail contact models necessarily have to consider “non-standard” phenomena (like the conformal contact, the presence of contaminants and friction modifiers, etc.) that deeply affect the global railway vehicle dynamics. Contemporaneously, the new models have to guarantee a good trade-off between accuracy and numerical efficiency to be effectively used into more general and complex multibody models and into real-time applications.

Looking at this scenario, this Special Session is focused on all the “non-standard” wheel-rail contact phenomena that should be taken into account in the multibody modelling of railway vehicles. The Special Session will cover, but not limited to, the following topics:

  • Non-Hertzian contact
  • Conformal contact;
  • Contact models for real-time applications;
  • Degraded adhesion;
  • Third body layer, contaminants and friction modifiers;
  • Fallen friction;
  • Adhesion recovery due to energy dissipation.

Both theoretical and experimental contributions will be highly appreciated. Theoretical papers will have to deal with the mathematical and physical description of the above-mentioned phenomena. An important role will be also played by the numerical efficiency of the proposed approaches. On the other hand, experimental works will have to focus on the model experimental validation and on innovative measurement techniques aimed at the model validation.
