This study presents possibilities to apply the numerical simulation of dynamic response for explosive (impulse) loads, caused by detonation of mine under the military armoured vehicle, acting on a crew member seating in chair, in order to determine methods to minimize the results of impact of vehicle body structure on the crew, mainly caused by it accelerations and overloads. Furthermore, this article presents factors, which have impact on numerical model and detonation phases necessary to conduct the mentioned above simulation. Information on physical values acting on the soldier and injuries resulting from such actions are important to understand how important element, improving physical protection of soldiers during mine detonation below the armoured military vehicle, is a chair. According to the dissertation "Development Of Lower Extremity Injury Criteria And Biomechanical Surrogate To Evaluate Military Vehicle Occupant Injury During An Explosive Blast Even" the most common injuries occurring during mine explosion under the military vehicles, eliminating soldiers from further service, include: sprain of vertebras, fracture of vertebra, light fracture of skull, brain shaking, brain concussion, fracture of tibia, damage to ilia, fracture of fibula bones. These injuries occur most often at the first two stages of explosion, called local and global effect.
