Biofidelic Responses of the THOR-NT and Hybrid III Based on Component Tests

Component tests were conducted in order to evaluate the biofidelity of the THOR-NT on the head, neck, thorax, abdomen, face, femur, and lower extremity (THOR-Lx). The biofidelity of the dummy was evaluated by comparing its biofidelic responses with the PMHS response corridors. Likewise, component tests on each body part of the Hybrid III were conducted, and the biofidelity between THOR-NT (THOR-Lx) and Hybrid III were compared. The THOR tests were subject to test procedures established by GESAC, Inc./NHTSA; the THOR-Lx tests were subject to NHTSA/VRTC procedures. Responses on the head and femur of both the THOR-NT and Hybrid III were within the PMHS response corridors. However, for other body parts - although each component of THOR-NT did not yield results that satisfied all the PMHS response corridors - the responses of THOR-NT were closer to the corridors than those of the Hybrid III.

Update of the WorldSID 50th Male Pelvic Injury Criterion and Risk Curve

Petit et al. 2015 and Lebarbé et al. 2016 reported on two studies where the injury mechanism and threshold of the sacroiliac joint were investigated in two slightly oblique crash test conditions from 18 Post Mortem Human Subjects (PMHS) tests. They concluded that the sacroiliac joint fractures were associated with pubic rami fractures. These latter being reported to occur first in the time history. Therefore it was recommended not to define a criterion specific for the sacroiliac joint. In 2012, injury risk curves were published for the WorldSID dummy by Petitjean et al. For the pelvis, dummy and PMHS paired tests from six configurations were used (n = 55). All of these configurations were pure lateral impacts. In addition, the sacroiliac joint and femur neck loads were not recorded, and the dummy used was the first production version (WorldSID revision 1). Since that time, the WorldSID was updated several times, including changes in the pelvis area.
