摘要

Blast wave overpressure has been associated with varyingrnlevels of traumatic brain injury in soldiers exposed tornblast loading. Although the actual injury mechanism isrnunknown, head kinematics are often used to evaluate thernpotential for head injury and provides an important linkrnbetween physical testing and detailed head models.rnThe goal of this study was to build on previous work torninvestigate head kinematics resulting from realistic blastrnloading. Improvised explosive devices have become morerncommon and have recently increased in size andrnexplosive capacity. This study examines the effect ofrnlarger explosive charges on head kinematics using arnvalidated simplified human body model.rnThe results of the parametric study showed that the headrnacceleration increased with decreased standoff. The headrninjury criterion threshold was exceeded in close proximityrnto blast for all explosive sizes tested. The mach stemrneffect from the ground reflection increased the potentialrninjury zone and caused a rapid increase in headrnacceleration thus leading to a much greater probability ofrninjury.
