Numerical Analysis of the Risk of Neck Injuries Caused By IED Explosion under the Vehicle in Military Environments

Abstract

Abstract:As a result of an explosion under a military vehicle, the risk of threat to life and health of the crew increases. Examination of this event in terms of the security of soldiers comes down to a complex analysis of the mutual interaction of the body of a soldier, seating and structural elements of the vehicle. As a result, shock wave impacts can cause tremor resulting from the construction of the vehicle and acceleration of the passenger's body. This study attempts to analyze the impact of an explosion of an improvised explosive device (IED) under the military vehicle with the risk of cervical spine injuries of soldiers. The analysis was carried out using numerical methods in the LS-DYNA program and was carried out taking into account the variable displacement values and acceleration recorded during the\ explosion. The study used a model of the body of a soldier in the form of a Hybrid III 50th Male Dummy.

Research of Vibrations of an Armoured Personnel Carrier Hull with FE Implementation

“…6 and 7) and three (Nos. 3,4,5) between the structural openings. The location of the accelerom eters was determined based on preliminary numerical tests.…”

“…However, FEM analysis gives much wider possibilities, such as modal analysis and evaluation of a structural response to static and dynamic loads. In [3,4], tests were carried out to determine crew and special equipment exposure to hazards such as direct fire, shrapnel, explosion of anti-tank mines, or improvised explosive devices. As a result, this approach allows for the development of solutions providing improved protection [5][6][7][8] and parameter optimisation [9] in order to minimise crew exposure as much as possible.…”

Experimental and Numerical Modal Analysis of the Military Vehicle Hull

“…FE analysis has become an essential tool to estimate structural responses under static and dynamic loads. Research is being conducted [1,2] to determine the exposure of crew and specialist equipment to such threats as direct fire, anti-tank mine explosion and improvised explosive devices. This approach allows the development of solutions to improve their protection [3][4][5], as well as optimization of its parameters to minimize the crew's exposure to threats as much as possible.…”
