Using ATB in Optimal Injury Prevention and Reduction 2003-01-2182

The use of digital human modeling in optimal injury prevention and reduction was studied and is described in this paper. The optimal injury prevention and reduction was treated as an optimization problem of a biomechanical system consisting of the safety unit and occupant. The issues of incorporating the Articulated Total Body (ATB) model, a digital human modeling tool, into an optimization process for the modeling and simulation of the biomechanics of the occupant were addressed. Modifications were made on the ATB source code, turning it into a subroutine that can be used in optimization. General considerations were also given to the creation of an interface that uses ATB as an analysis tool in the approximate optimizations. As a practical engineering application, the optimization of the ejection seat cushion impact properties for the minimization of the risk of spinal injuries was investigated.
