Pelvic Biomechanical Response and Padding Benefits in Side Impact Based on a Cadaveric Test Series 933128
The frequency of pelvic fractures is 10%-14% in side impact crashes. In this study, seventeen side impact sled tests were performed using a Heidelberg-type seat fixture. The pelvis along with the rest of the torso impacted a sidewall in these tests. This series of runs provided a good test of injury criteria performance for a variety of impact surfaces. Pelvic injury criteria based on force, acceleration, compression, and the viscous criterion were evaluated. Force was found to be a good criterion according to both the Weibull and Logist analysis. A promising new injury criterion tested was “Average Force” (Favg). It reflects the rate of momentum transfer to the pelvis during a side impact. The slope of the pelvic momentum trace, from 10 to 90% of its peak, is the time rate of change of momentum, and has the dimension of force. In a 32 km/h (20 mph) impact, Favg is 5 kN for a 25% probability of an AIS 2 pelvic injury (maximum likelihood 0.0135).
