AB The present study is focused on the dynamic simulation of a car frontal crash against a lateralprotection system for semitrailers. This system is a barrier fixed laterally to each side insemitrailers, designed to reduce damages on car passengers in case of lateral collision. Fromthe basis of an already existing design, different designs and finite element models wherecreated, adapting the system to the European regulation UNECE nº 73, concerning lateralprotection devices’ homologation. Finite element models were developed and differentmaterials were considered on the metallic barrier beams. Then, crash simulations using thesoftware LS-DYNA were performed, where a passenger car Toyota Yaris Sedan (2010model) was impacted against the barrier at 50 km/h, 90 km/h and 120 km/h. Results such asmaximum car displacements and deceleration on passengers could be analysed in thesesimulations. It was assessed the possibility of achieving a weight reduction of the barrier bymeans of design and material modifications.
