Reverse Engineering Of A Military Vehicle Body And The Simulation Of It’s Door’s Anti-ballistic Performance

In modern war, the military vehicles are playing an increasing important role more than transportation tool. As the basic form of war is changing, military vehicle undertake more and more service and mission. On one side, military vehicles confront a big threaten not only in the battlefield, but also outside the war zone. On the other side, the weight of military vehicle directly determines its mobility and off-road ability. Therefore, it is significant to improve the safety performance of military vehicles while optimizing the lightweight in an utmost way.First, using the reverse engineering method, a model of "Warrior" designed by Dongfeng Company is scanned to obtain the CAD model. Based on the "Warrior" CAD model to increase the safety performance of military vehicles against the impacts from land mine and bullets, here the finite element method is used to research the penetration process of bullet through plate, also a comparison between plates with different thickness has been conducted to research how the anti-penetration performance was varied by the thickness. This paper is of reference value for CAD modeling of military vehicle and its trajectory-protection design.
