Abstract

During the land operations, the enemy's gunnery is the primary threat. For the military vehicle, the bulletproof effect is the one of the important issues regarding the safety of soldiers on duty. Recently, the advanced military vehicles have planned to install armor plates. However, due to the budget problem, it is difficult to equip the protection systems. Hence, the optimum approach to increase bulletproof capability is essential. In this paper, the optimum thickness and component of the armor of military vehicles were evaluated by using finite element analysis for bullet impact effects. To achieve this aim, 7.62mm NATO bullet, 1.6mm steel and Kevlar-29 composite have been modeled and the simulations were conducted with various thickness cases by using MSC Nastran sol 700. Consequently, it was revealed that Kevlar-29 45 Layer is appropriate thickness for 7.62 bulletproof. Furthermore, Kevlar-29 in front of steel was effective by comparison with the back of steel for bulletproof.
