BIOFIDELITY AND INJURY ASSESSMENT IN EUROSID I AND BIOSID

Side impact pendulum tests were conducted on Eurosid I and Biosid to assess the biofidelity of the thorax, abdomen and pelvis, and determine injury tolerance levels. Each body region was impacted at 4.5, 6.7, and 9.4 m/s using test conditions which duplicate cadaver impacts with a 15 cm flat-circular 23.4 kg rigid mass. The cadaver database establishes human response and injury risk assessment in side impact. Both dummies showed better biofidelity when compared to the lowest-speed cadaver response corridor. At higher speeds, peak force was substantially higher. The Eurosid I abdomen had the most dissimilar response and lacks biofidelity. Overall, Biosid has better biofidelity than Eurosid I with an average 21% lower peak load and a closer match to the duration of cadaver impact responses for the three body regions. There was a significant correlation between cadaver and dummy responses in similar tests, so injury risk can be assessed in the dummies. Eurosid I chest deflection was not sufficient to prevent bottoming in high-speed tests. However, the peak viscous response (VC) occurs before rib bottoming and enables chest injury assessment for all of the pendulum impacts. The research establishes a technical basis for injury tolerance levels in Eurosid I and Biosid. For the covering abstract of the conference see IRRD 882980.
