During the MBS Tech Days 2021, Björn Pålsson from the Chalmers University-of-Technology held a presentation called "Modelling and Simulation of Dynamic Interaction between a Rail Vehicle and a Railway Turnout Assembly using Simpack’s Linear and Non-linear Flextrack Modules".

This presentation will provide examples of the modeling and simulation of dynamic vehicle-track interaction in railway switches and crossings (S&C, turnouts) using Simpack's linear and non-linear flex track modules. 

In this presentation the

• modeling steps taken to implement the S&C models will be presented 
• suitability of the different flex track modules for various analysis applications will be discussed
• modeling of flex track will be compared to the use of standard co-running track models
• simulation results will be compared to measured wheel-rail contact forces and track responses in S&C

@BP is an Associate Professor in Railway Mechanics at the Chalmers University of Technology in Göteborg, Sweden. Björn's main research interests are modeling and simulation of dynamic vehicle-track interaction and ensuing track degradation, focusing on switches and crossings (S&C, turnouts). Björn holds an MSc in mechanical engineering from Chalmers University and completed his Ph.D. thesis "Optimisation of Railway Switches and Crossings" in 2014.
