Comparison of the simplified GHBMC to PMHS kinematics in far-side impact
Paper in proceedings, 2019

Far-side impacts represent 9.5% of all automobile crashes and 8.3% of all MAIS3+ injuries. This type of event generates loads that challenge current restraint systems by setting the occupant in an inward motion. This complex motion, influenced by a number of restraint and impact parameters, often results in a loss of shoulder-to-belt contact. Existing Anthropomorphic Test Devices show limited ability to represent post-mortem human subject kinematics and sensitivity to restraint and impact parameters. Therefore, Human Body Models can play a fundamental role in understanding human response in this impact scenario. This study compares the simplified GHBMC to previously published post-mortem human subject kinematics and sensitivity to restraint and impact parameters. Results show that, in general, the simplified GHBMC captures lateral excursion in oblique impact conditions but overpredicts in purely lateral impact conditions. The simplified GHBMC shows post-mortem human subject like sensitivities to changes in ?V and the use of pretensioner but no sensitivity to changes in impact direction. The human body model performs similarly to other previously published HBMs and obtains a “good” CORA score. However, the surrogate does not represent post-mortem human subject shoulder-to-belt interaction in all configurations.
