전투차량의 피해 정도를 계산하기 위한 수치해석적 접근법

In order to reduce the number of casualties by improving the survivability of the combat vehicle, the vulnerability analysis of the combat vehicle is needed. However, the actual test for the vulnerability analysis requires large experimental space and expensive equipment costs long time and large expense. It is needed to develop a new method that can replace the actual test. In the paper, we suggested a new approach to analyzing the vulnerability using the M&S method instead of the actual test. To analyze the vulnerability, the shot line analysis is performed to find out which part is penetrated by the bullet. The component of the parts is simplified to “Single- Target”, “Double-Target”, “Air gapped-Target” and can be performed the penetration analysis using the ANSYS Explicit Dynamics. The penetration depth and the residual velocity of the bullet are calculated by analyzing penetration of each part of the combat vehicle. The penetration data calculated the penetration analysis can be used to define the damage level of the combat vehicle. The purpose of this paper is to collect penetration data for various targets and bullets. And “7.62mmAP” is used as the bullet, “7075-T6” is used as a target.
