Abstract:

This project sought to perform an initial evaluation of the usability, stability, and potential injury prediction capabilities for two human body models (GHBMC-M50-O and GHBMC-M50-OS) and the NHTSA THOR FE anthropomorphic test device model in occupant postures that will become more possible with automated driving systems (ADS). Postures examined degrees of seat recline, degrees of inboard seat rotation, occupants turned in their seats, and occupants leaning against the belts in sleep-like posture. Collision scenarios included moving deformable barrier impacts at PDOFs around the vehicle. All simulations were performed with the occupant seated in the right front passenger position. Restraints included a front passenger air bag, a side curtain air bag, a side torso air bag, and a 3-point seat belt. Approximately 175 full vehicle simulations were performed and analyzed. The primary lessons learned are: The design of the THOR pelvis constrains the maximum degree effectively reclined; GHBMC M50-O and OS models are too stiff for natural gravity settling into reclined positions; the GHBMC M50-O model required substantial computational effort to position into a reclined posture; the GHBMC M50-OS model exhibited negative volume errors in the abdomen from the belt loading; the GHBMC M50-OS models lacks continuity constraints between superficial tissue, skeleton, and internal organs; the GHBMC M50-OS model tended to be more prone to submarining than the THOR FE model. The models also exhibited differences in pelvis rotation, lumbar spine flexion, interaction with the seat pan, and interaction with the lap belt.
