During the MBS Tech Days 2021, Kamil Sazgetdinov from VIRTUAL VEHICLE Research held a presentation called "Simpack Multibody-Dynamics Model-Based Methodology for the Holistic Track Damage Evolution Prediction in Railway Turnouts".

In his presentation, Kamil talks about how railway turnouts feature discontinuities in wheel-rail contact geometry and track stiffness, which results in large dynamic wheel-rail contact forces, leading to a degradation of the rail surfaces and track irregularities over time. Analysis of the literature shows that researchers focus primarily on one damage mechanism at the time. However, the interplay and interconnection between different track damage patterns have not yet been addressed to the same extent.

This presentation demonstrates a novel developed methodology based on the Simpack multibody-dynamics model. Thus, showing how the model can calculate holistic predictions for accumulated track damage in railway turnouts, account for the interplay and interaction between different damage patterns, e.g., such as the development of track irregularities due to ballast and subsoil settlement, and rail profile changes due to plastic deformation and wear.

M.Sc. @KS is currently a Junior Researcher at the Virtual Vehicle Research GmbH within the Department Rail and doctoral student at the Graz University of Technology in Graz, Austria. Kamil's main research areas include vehicle-track interaction, multibody dynamics, and track damage modeling for the railway turnouts application.  ​​​​​​​
