THOR-AV 5F, a modified THOR-5F dummy, was designed to represent both upright and
reclined occupants in vehicle crashworthiness studies. The dummy was evaluated
in four test conditions: a) 25° seatback, 15 km/h, b) 25° seatback, 32 km/h, c)
45° seatback, 15 km/h, d) 45° seatback, 32 km/h. The dummy’s biomechanical
responses were compared against those of postmortem human subjects (PMHS) tested
in the same test conditions. The latest National Highway Traffic Safety
Administration (NHTSA) BioRank method was used to provide a biofidelity ranking
score (BRS) for each data channel in the tests to assess the dummy’s biofidelity
objectively. The evaluation was categorized into two groups: restraint system
and dummy. In the four test conditions, the restraint system showed good
biofidelity with BRS scores of 1.49, 1.47, 1.15, and 1.79, respectively. The
THOR-AV 5F demonstrated excellent biofidelity in three test conditions: 25°
seatback, 15 km/h (BRS = 0.76); 25° seatback, 32 km/h (BRS = 0.89); and 45°
seatback, 32 km/h (BRS = 0.93). In the fourth test condition, 45° seatback, 15
km/h, the dummy demonstrated good biofidelity with a BRS score of 1.06. The
dummy demonstrated good durability. No damage was identified with a full
inspection conducted after the tests.
