Trabajo presentado en: R-Evolucionando el transporte, XIV Congreso de Ingeniería del Transporte (CIT 2021), realizado en modalidad online los días 6, 7 y 8 de julio de 2021, organizado por la Universidad de Burgos
The present study is focused on the dynamic simulation of a car frontal crash against a lateral
protection system for semitrailers. This system is a barrier fixed laterally to each side in
semitrailers, designed to reduce damages on car passengers in case of lateral collision. From
the basis of an already existing design, different designs and finite element models where
created, adapting the system to the European regulation UNECE nº 73, concerning lateral
protection devices’ homologation. Finite element models were developed and different
materials were considered on the metallic barrier beams. Then, crash simulations using the
software LS-DYNA were performed, where a passenger car Toyota Yaris Sedan (2010
model) was impacted against the barrier at 50 km/h, 90 km/h and 120 km/h. Results such as
maximum car displacements and deceleration on passengers could be analysed in these
simulations. It was assessed the possibility of achieving a weight reduction of the barrier by
means of design and material modifications.
