Background.
Occupant injuries in rollover crashes are associated with vehicle structural performance, as well as the restraint system design.
For a better understanding of the occupant kinematics and injury index in certain rollover crash, it is essential to carry out dynamic vehicle rollover simulation with dummy included.
Objective.
This study focused on effects of curtain airbag (CAB) parameters on occupant kinematics and injury indexes in a rollover crash.
Besides, optimized parameters of the CAB were proposed for the purpose of decreasing the occupant injuries in such rollover scenario.
Method and Material.
The vehicle motion from the physical test was introduced as the input for the numerical simulation, and the 50% Hybrid III dummy model from the MADYMO database was imported into a simulation model.
The restraint system, including a validated CAB module, was introduced for occupant kinematics simulation and injury evaluation.
TTF setting, maximum inflator pressure, and protection area of the CAB were analysed.
Results.
After introducing the curtain airbag, the maximum head acceleration was reduced from 91.60 g to 49.52 g, and the neck Mx and neck Fz were reduced significantly.
Among these CAB parameters, the TTF setting had the largest effect on the head acceleration which could reduce 8.6 g furthermore after optimization.
The neck Fz was decreased from 3766.48 N to 2571.77 N after optimization of CAB protection area.
Conclusions.
Avoiding hard contact is critical for the occupant protection in the rollover crashes.
The simulation results indicated that occupant kinematics and certain injury indexes were improved with the help of CAB in such rollover scenario.
Appropriate TTF setting and inflator selection could benefit occupant kinematics and injury indexes.
Besides, it was advised to optimize the curtain airbag thickness around the head contact area to improve head and neck injury indexes.
