Multibody simulation benchmark for dynamic vehicle-track interaction in switches and crossings



Dr Yann Bezin and Dr Björn Pålsson from The University of Huddersfield (UK) and from Chalmers University of Technology (Sweden) respectively, organised a benchmark on the dynamic vehicle-track interaction prediction in switches and crossings using multibody system approach.

The benchmark was first presented at the 2019 IAVSD International Symposium on Dynamics of Vehicles on Roads and Tracks, in Gothenburg, Sweden.

The main purpose of the benchmark is to compare the current software solutions available for such exercise, share and promote a better understanding of the state-of-the-art, and promote ideas and stimulation for developing software capabilities in this field.

A workshop, originally planned over two days, was replaced by two 3-hours online sessions due to COVID-19 situation, and was well attended by over 35 participants. Nineteen sets of results have been received so far from eighteen independent participants, including nine independent software. The exercise has been more widely followed by thirty eight contacted organisations from academia (23), industry (8) and software developers (7), making this benchmark very well followed by the entire community and practicing users.

The result of the benchmark will be published in a Special Issue of Vehicle System Dynamics Journal that will also include further information from each participant methods statements. Additionally, a collection of about fifteen scientific papers will make part of this special issue, extending the value of the benchmark by exploring further a wide range of aspects such as vehicle suspension effects, track modelling approaches and variability from the systems parameters.
