UMTRI reported on PMHS and WorldSID 50th male dummy abdomen comparison testing using a two-mass sled system to obtain the typical side impact crash signature. Biofidelity targets were generated using the techniques from the ISO frontal biofidelity group chaired by Matthieu Lebarbe. Results indicate that the WorldSID abdomen does not deform as much as the PMHS under similar loading conditions. The WorldSID pelvis may need to be less stiff and have a less tightly coupled mass. Additionally, the thigh flesh may also be too stiff. The full analysis and results are published in ESV Paper 11-0080.

NHTSA presented testing conducted by UMTRI comparing PMHS thorax and pelvic responses to WorldSID 50th male dummy responses. The PMHS and dummies were impacted by a padded wall, first at 3 m/s and then at 8 m/s. It was found that the WorldSID abdomen does not deform as much as the PMHS abdomen under similar conditions and is somewhat less rate sensitive. The WorldSID pelvis forces were higher than the PMHS response corridors sat 8 m/s, but the WorldSID pelvis Y-axis was within the response corridors, suggesting that the WorldSID pelvis may too stiff. Future testing may include a comparison study of the 5th female, depending on the availability of PMHS.
