Description
Summary:Explosion from an anti-tank mines or improvised explosive devices are recognized as one of the lethal threat towards occupants inside an armoured vehicle. The detonation of these threats creates high intensity blast waves that were transmitted to the occupant through vehicle structures and seats. Minimizing the occupant's casualty can be achieved by properly dissipating the shock waves exerted to the vehicle. It is important to distinguish the contributing factors that affectted the behavior of the blast wave so that proper reduction on the shock waves can be achieved. In this paper, three factors such as occupant seating height, charge weight placement and the Hopkinson-Cranz blast scaling were studied using numerical simulations. Design of experiment (DOE) was utilized to determine the ranks and interactions between each factor from the most influential on the results to the least affects towards the results. From the results it was found that the seating position plays a significant role in reduction of the shock response towards the finite element dummy model.
