The present study evaluated the kinematics of the Global Human Body Model Consortium (GHBMC) model, under frontal impact. Resultant acceleration data from simulations at head center of gravity (CG), T1, sternum, T12, and sacrum were compared with sled test responses. The objectives of the present study were to normalize the experimental data, qualitatively compare the simulation kinematics to that of the PMHS response, and quantify the goodness‐of‐fit using correlation analyses (CORA). Kinematics data from restrained eight PMHS tests – low (3.3 m/s), and medium (6.7 m/s) – were used to evaluate the biofidelity of the GHMBC model under frontal impact. The experimental data were normalized to represent 50th percentile male population, to minimize response variations due to demographics. The restrained GHBMC model was positioned with its standard posture on a rigid seat. Simulations were performed using two different input speeds – low, and medium ‐ under frontal impact conditions. Qualitative observation of the kinematics between simulations and experiments indicated a good match. CORA ratings ranged from 0.51 to 0.78, and 0.53 to 0.75 for the low, and medium speed cases respectively, indicating acceptable kinematic biofidelity of the model under frontal impact.
