Application of Mathematical Modeling in Potentially Survivable Blast Threats in Military Vehicles

摘要

Crew injuries and fatalities of military personnel in vehicles are a significant concern in the U.S operations in Iraq and Afghanistan. And the predominant cause is Improvised Explosive Device (IED) attacks on vehicles. A computational model using MADYMO, a mathematical dynamics modeling software, which utilizes lumped parameter, rigid body and finite element methodologies, was developed for the study. MADYMO simulations were performed with the correlated MADYMO model to understand the occupant injury values under the influence of various generic mine blast pulses and seat system energy management design parameters. In addition, the concepts of Effective G and Delta V to relate structural performance to occupant injury risk were investigated.
