Side Impact Assessment and Comparison of Appropriate Size and Age Equivalent Porcine Surrogates to Scaled Human Side Impact Response Biofidelity Corridors.

Abstract

Analysis and validation of current scaling relationships and existing response corridors using animal surrogate test data is valuable, and may lead to the development of new or improved scaling relationships. For this reason, lateral pendulum impact testing of appropriate size cadaveric porcine surrogates of human 3-year-old, 6-year-old, 10-year-old, and 50th percentile male age equivalence, were performed at the thorax and abdomen body regions to compare swine test data to already established human lateral impact response corridors scaled from the 50th percentile human adult male to the pediatric level to establish viability of current scaling laws. Appropriate Porcine Surrogate Equivalents PSE for the human 3-year-old, 6-year-old, 10-year-old, and 50th percentile male, based on whole body mass, were established. A series of lateral impact thorax and abdomen pendulum testing was performed based on previously established scaled lateral impact assessment test protocols. The PSE thorax and abdominal impact response data were assessed against previously established scaled human thorax lateral impact response corridors and scaled abdominal oblique impact response corridors for the 3-year-old, 6-year-old, 10-year-old, and 50th percentile human male based on lateral pendulum impact testing. The overall findings of the current study confirm that lateral impact force response of the thorax and abdomen of appropriate weight porcine surrogates established for human-equivalent-age 3-year-old, 6-year-old, 10-year-old, and 50th adult male are consistent with the previously established human scaled lateral impact response corridors). Porcine surrogate biomechanics testing can prove to be a powerful research means to further characterize and understand injury and response in lateral impact.
