Vehicle security barriers are a crucial component in preventing vehicle-ramming attacks in pedestrian zones. To ensure the effectiveness of these barriers, they must be designed and installed to protect against specific threat levels of related to vehicle mass and category and impact velocity. However, the performance of barriers against vehicle impact is typically certified through physical crash tests, which are limited in number due to their high cost. This limitation results in a scarcity of experimental validation data, making it challenging to assess the margins of the design. To address this issue, numerical simulations have emerged as a viable alternative for analysing the performance of security barriers. Generic vehicle models based on FE have been developed to represent vehicles of specific categories, allowing for the characterization of vehicle impact loads on barriers. These models are designed to be computationally efficient and have been validated through comparisons to crash tests. This paper presents first, the threat of hostile vehicles and its mitigation. It describes the concept of the generalisation of the vehicle models, the details of the models (vehicle categories N1, N2A/N3D and N3G) and their validation with dynamic and impact tests.
