Abstract:The cause of serious and fatal thoracic injuries in passenger vehicle rollover crashes is currently not well understood. Previous research on thoracic injuries resulting from rollover crashes have focused primarily on statistical analysis of crash data. This study seeks to develop a better understanding of where in the rollover sequence thoracic injuries may occur. To do this, a real-world passenger vehicle rollover crash where the driver sustained serious bilateral thoracic injuries was reconstructed. Multi-body analysis was used to determine the vehicle's pre-trip trajectory and to obtain the vehicle's position and kinematics at the point of trip. This information was then used to prescribe the motion of the vehicle in a finite element analysis. A finite element model of the EuroSID-2re anthropomorphic test device was placed in the driver's seat. Four simulations, each with the anthropomorphic test device positioned in different postures, were performed. Rib deflection, spinal acceleration, and thoracic impact velocity were obtained from the anthropomorphic test device and compared to existing thoracic injury assessment reference values. From the analysis, lateral thoracic impact velocity indicates that a serious thoracic injury is likely to have occurred when the driver impacted the centre console during the vehicle's fourth quarter-turn.
