Small Female Acceleration Response Corridors and Updated THOR-05F BioRank: Preliminary Results from Nearside Frontal Oblique Impact Tests

Authors: Jared Koser, Tyler Rooks, Narayan Yoganandan, Medical College of Wisconsin

Abstract

The objective of the study was to develop response corridors of small female post-mortem human subjects (PMHS) and evaluate the biofidelity of the THOR-05F in nearside oblique frontal impacts using the Biofidelity Ranking System (BRS). Matched pair tests were conducted with five restrained PMHS at 8.4 m/s and three repeat tests with the THOR-05F under similar conditions. Accelerations of the upper and lower thoracic spine, lumbar spine, and pelvis were used to develop corridors using the traditional mean ± 1 standard deviation (SD) method. They were used to evaluate the biofidelity of the THOR-05F. The mean ± 1SD BRS scores ranged from 0.59 ± 0.01 to 1.09 ± 0.02 for different regions of the spine and pelvis, indicating excellent biofidelity. Additional analyses using BRS for different signals and obliquities are needed to further evaluate the biofidelity of the THOR-05F.
