Abstract

Catastrophic neck compression and flexion injuries with quadriplegia are foreseeable outcomes of rollover crashes. However, current static regulatory tests cannot directly predict real-world rollover neck injuries. In this study, a dynamic test was developed and integrated bending moment (IBM) criteria proposed that can replicate/predict rollover neck flexion injuries with the Hybrid III dummy, upper and lower neck load cells, and a lateral vehicle camera. Platen drop tests were performed, revealing realistic pre-trip occupant positioning and a relationship between upper and lower neck loading. Dynamic rollover tests of 5 cars (FMVSS roof strength to weight ratio (SWR) range = 2.3 to 5.1) showed reduced neck flexion injury potential with increasing SWR and minimum roof SWR threshold of about 3.5 consistent with other proposed rollover injury criteria.
