Abstract:

Neck-injuries were investigated in whiplash test by two different occupant models (the THUMS (total human model for safety) and BioRID II model) to design a better anti-whiplash seat with occupant-neck protection. A seat finite element model was established to simulate whiplash test according to the China New
Car Assessment Programme (C-NCAP) (2015 Ed) evaluation procedures and principles of whiplash test score. The dynamic responses and neck-injuries were compared for the two models. The results show that the THUMS model has better biofidelity with larger neck injury index (NIC), neck shear force, and the torque and tension on neck than the BioRID II model. These will provide valuable references to improve biological fidelity of the BioRID II model.
