制导杀爆弹毁伤效能评估的应用研究

基于真实目标等效结构研究制导杀爆弹毁伤效能评估的应用.针对红外成像和GPS两种制导模式，分析末端弹道特征对于确定弹药研究毁伤效能与引信炸高、制导精度之间的联系.通过分析结果可见，采用红外成像制导模式，炸点随着炸高的提高离瞄准点的距离逐渐变远，破片群难以命中目标；采用GPS制导模式，炸点可通过弹载计算机计算调整炸点于目标上方，破片群向下可命中目标，对目标的毁伤效果较好；所以，弹药的毁伤效能除了与战斗部、引信有关，还与导引头的制导模式相关.通过仿真分析，制导模式对战斗部动爆威力场影响不大，因此在战斗部研制过程中可不考虑弹药的制导模式，而只采用动爆条件下的毁伤幅员对战斗部的毁伤效能进行考核，以优选出最佳战斗部结构和炸高. 

Applied Research on Damage Effectiveness Evaluation of Guided Explosive Bomb

Based on the equivalent structure of real targets,the application of damage effectiveness evaluation of guided explosive bombs was studied. For infrared imaging and GPS guidance modes, the end ballistic characters were analyzed, and for designated power warhead, the relationship between the damage effectiveness and fuze explosion height and guidance precision was studied. From the simulation results, using the infrared image guidance mode, when the explosion height was increased, the explosion point was farther away from aiming point, it was harder for the fragments to hit the target;using GPS guidance mode, with the bomb embedded system, the explosion point could be adjusted to be just above the target, so the fragments could hit the target below and get better damage effect; so the damage effectiveness was not only related to warhead and fuze, but also related to guidance mode.From simulation analysis, the guidance mode has little effect on the dynamic power field of the warhead, so in the process of warhead research, in order to get the best warhead structure and explosion height, the guidancemode can be ignored and damage dimensionalities alone can be used to evaluate the warhead damage effectiveness.
