Assessment of the Accuracy of Certain Reduced Order Models Used in the Prediction of Occupant Injury During Underbody Blast Events (Briefing Charts)

摘要

It is a well known fact that underbody blasts have become one of the most widespread reasons for warfighter casualties in recent wars. -Spinal injuries to occupants have particularly increased in theater from these roadside blast incidents, followed by tibia and lower leg injuries. The most common occupant injuries in these extremely short duration events arise out of the very high vertical acceleration of vehicle due to its close proximity to hot high pressure gases from the blast. It is of considerable interest to developers of military vehicles to assess occupant injury risk due to blast loading in the early phase of the design process.
