SUMMARYThe project ‘Assessment of vehicle-track interaction with special reference to dynamic safety in operating conditions’ (DYSAF), and supported as Brite-Euram Programme investigates dynamic phenomena at stake in derailment and overturning of vehicles. The project is led by a consortium of end-users, manufacturers of vehicles and experts in railway dynamics simulation and measurement techniques from five European countries.Among the main research items of DYSAF is also ‘Modelling of dynamic interaction, close to limits’ performed with multibody software. Compared to previously published benchmarks of codes applied to freight traffic situations/1/at relatively low speed, DYSAF focuses on situations of high speed with short dynamic components compared to quasi-stationary results.
