Study on the Characteristics of Rollover Injury of Passenger on the Passenger Side of an Off-Road Vehicle

In order to study the injury characteristics of the passenger-side occupant in the process of near-ground side ramp rollover, a finite element model of an off-road vehicle was established, and the acceleration of the center of mass of the vehicle rollover was obtained through simulation, and the accuracy of the model was verified through real vehicle rollover test. Hybrid III 50% male dummy was placed in the three rows of seats on the passenger side, and the restraint system was the same as that of the original vehicle, and the damage to various parts of the dummy was obtained for comparative analysis. The study shows that: the peak injury moments of different positions are similar, only the peak injury moments of the head and chest of the rear dummy appear earlier; the rear occupant's body dives and the neck is compressed, resulting in excessive axial force on the neck, and the subsequent improvement should focus on the restraint system.
