根据降阶态评估方法实施过程,以主战坦克武器系统为对象,进行降阶态易损性分析与评估仿真。在深入分析武器系统各子系统功能的基础上,进行武器系统易损性分析,确定了反应系统功能丧失降阶状态的DS 值,并利用由上至下的演绎法构建了功能毁伤树;利用蒙特卡洛随机模拟方法,对二次破片瞬间速度进行模拟,实现弹目交汇处理。利用VC 6.0 平台开发了部件级易损性评估仿真系统,进行了功能分析与功能模块设计,并进行具体实例运算与分析。结果表明,部件与命中点之间的相对位置关系,以及是否有遮蔽部件,直接影响部件的毁伤状态。进行装备部件级易损性分析时,不仅要考虑部件易损面积,还须考虑防护与遮蔽。本文研究内容是装甲装备目标部件级易损性评估的重要部分,可为装备战场损伤快速评估与装备精确保障仿真提供基础。
Vulnerability analysis and assessment simulation was carried out with main-battle tank weapon system as the research object according to implementation procedure of degraded state (DS) assessment method. First, DS values revealing loss of functions of each sub-system were identified based on analysis of each sub-system functions. Function damage trees were created using deductive method from top to bottom. To realize threat-target interaction, instant velocity of debris behind armor was simulated using Monte Carlo stochastic simulation method. Component level vulnerability assessment simulation system was developed by Visual C 6.0 platform. Function modules were designed, and one case was run and simulated results were analyzed. It showed that relative space between one component and hit point and whether there are defense components directly affect damage state of the component. In component level vulnerability analysis, not only vulnerability area but also defense and shelter need to be considered. Research in this paper is one important part of component level vulnerability assessment of armored equipment and may provide a foundation for battle damage assessment and exact support simulation.
