中文摘要:
武器装备部件级战场损伤评估是实现装备精确保障仿真与战时精确预测的基础。以榴弹破片对付主战坦克为例，采用有限元离散法提出一种的弹目交会计算模型，建立了以概率形式表示的破片打击下部件毁伤准则。确定了一定条件下的火炮身管炮口与炮塔附近处损坏的临界侵彻深度，分别是35mm和85mm。编制了主战坦克与榴弹破片的有限元离散交会计算程序，并进行了示例计算。研究结果也适用于榴弹破片对付其他装备部件的损伤评估，从而为战场修复与精确维修保障提供支撑。
English Summary:
Battle damage assessment of weapon equipment component level is the foundation to realize exact equipment support simulation during the war, as well as the basis to forecast wartime exact service. Taking the high explosive shell against main-battle tank as example, an interaction model was built for target and warhead based on finite element analysis. Based on a component damage criteria described with probability form, the main-battle tank barrel's critical damage thickness was analyzed. Results show that the critical penetration depth of gun barrel muzzle and turret is 35mm and 85mm respectively. A finite element interaction program was developed for the main-battle tank and grenade fragments, and carried out an example calculation. Research results can be applied to damage assessment of grenade fragment against other weapon equipment components, which provides support for the battle repair and accurate maintenance support.
