    Análisis de los refuerzos estructurales no convencionales en la deformación de bisagra plástica, en colisiones de vuelco de autobuses según el procedimiento de la CEPE R66, por medio de simulación computacional empleando software CAE

    This thesis work was carried out with the aim of analysing the influence of nonconventional structural reinforcements on plastic hinge deformation in bus rollover accidents. For this purpose, an interprovincial bus was modelled using the Ecuadorian technical standard NTE INEN 1668 as a tool. Subsequently, ANSYS LS-DYNA RESEARCH was used to simulate the structural elements of the model. The rollover test simulations are carried out following the specifications of the UNECE R66 Regulation with the objective of evaluating the impact resistance and occupant safety in the event of a vehicle rollover. The research concluded that the use of structural reinforcements significantly improved the strength and safety in bus rollover crashes. Computational simulation made it possible to analyse the deformation of the bus structure. In addition, the use of non-conventional structural reinforcements, such as multicell and sidewall-floor joints, proved to be an alternative to strengthen the bus body in rollover collisions. On the other hand, the use of aluminium foam as structural reinforcement did not provide a significant improvement in the strength and safety in bus rollover collisions.
