Biomechanical Modeling
Although it will never be possible to eliminate traffic accidents completely, our researchers work to reduce the injuries to drivers and passengers associated with those accidents. When traffic accidents occur, the head, neck, and thorax are particularly vulnerable. We have developed modeling techniques for predicting injuries to these areas. Our staff has developed techniques to gain a better understanding of the mechanisms that cause trauma to occur during a crash. To support NHTSA's efforts in the area of biomechanics, we have developed an advanced finite element model frontal crash test dummy named THOR. THOR is an effective tool for whole body trauma assessment in a variety of automotive occupant restraint environments. This modeling technique provides a valuable cost-effective tool for crash safety research. In addition to the THOR model, we have also conducted research on modeling and analysis of the human head during crashes. The objective of this research is to evaluate injury to the soft tissue of the brain using simplified finite element models of the brain together with dynamic load data from actual crash tests.
