Summary:

Even though the rollover is not the most frequent type ofaccident, it is of the greatest significance with respect to injuryand trauma caused to the vehicle occupants. The need to reducedeath incidence and serious injuries has increased the importanceof computational simulations and prototype testing.This study presents finite element model to simulate rolloverevents and to predict possible injuries caused in the head, neck,thorax and cervical spine. Numerical models of a sport utilityvehicle (SUV) are simulated including anthropomorphic dummy torepresent the driver. The injury risks and traumas are verified tothe driver considering belted and unbelted dummies.The computational methodology developed proved to be efficientfor the evaluation of the vehicle's roof structure in rolloverevents. Regarding the computational results, some standards andprocedures which are broadly used by the automotive industry toevaluate the vehicle's roof resistance, cannot prevent theoccurrence of injuries and traumas to the occupants. Moreover,according to the results of numerical simulations, it is suggestedthat the load required evaluating the car's roof resistanceshould be increased. It is shown that numerical methods can be usedto assess the structure of the vehicle and verifying thedriver's injury risk, reducing the amount of experimental teststo be performed
