Abstract:Oblique impact configurations account for a significant amount of real-world accidents. Compared to co-linear frontal crash configurations, these impacts have different occupant kinematics and vehicle intrusion patterns. Consequently, a new oblique impact test is being developed and investigated by the National Highway Traffic Safety Administration. Variations in impact conditions and occupant seating positions are immanent in full-scale crash testing. For example, offset moving deformable barrier (OMDB) impact velocity and occupant seating position can only be controlled within certain limits. Therefore, it is important to understand the effect of relevant parameters related to NHTSA’s advanced test and occupant positioning procedure. Finite element simulations, consisting of detailed computer models of a vehicle, the OMDB, the Test Device for Human Occupant Restraints (THOR), and relevant restraints and interiors, were used by the Center for Collision Safety and Analysis at the George Mason University to conduct this research funded by NHTSA. Advanced design-of-experiment (DoE) methods were applied to determine the importance of parameters and their effect on the vehicle and occupant criteria.
