A numerical framework to support the certification of barrier testing

Abstract: 

This report describes the numerical framework to study the impact of vehicles on barriers, as part of the vehicle ramming protection strategy development. The numerical framework covers the set-up of the desired parameters of the model and also the computational efficiency of the analysis. Numerical results of passengers and heavy weight vehicle impact against bollards are presented. Finally, we discuss how the numerical simulations can assist in obtaining a better certification of the Hostile Vehicle Mitigation (HVM) systems via guidelines and enhancement of the existing specifications. It is expressed the clear need to develop European models for different vehicle types to support the development of barriers and to foster the European market of barriers.
