摘要
旋转式定向战斗部集高破片杀伤动能利用率和高炸药爆炸能量利用率的优势于一身,受到研究学者的广泛关注。对弹目交会的研究是旋转式定向战斗部发挥旋转定向功效的重要前提,为此,建立了含有破片毁伤场的空空六自由度弹目交会模型,利用非旋转式轴对称装药的破片毁伤场,模拟旋转式非轴对称装药战斗部旋转任意角度后破片的飞散状态,并通过MATLAB进行了仿真。最终计算出了旋转式定向战斗部弹目交会时的最大毁伤效能下对应的起爆延迟时间和旋转角,并给出旋转机构的响应速度范围的具体计算方法,为旋转式定向战斗部引战配合设计提供了重要理论依据。
The rotary directional warhead has the advantages of high fragment killing kinetic energy utilization and high explosive explosion energy utilization,which has attracted extensive attention of researchers.The study of missile target rendezvous is an important prerequisite for the rotating directional warhead to exert its rotating directional effect,therefore,an air-to-air six degree of freedom missile target rendezvous model with fragment damage field is established.Using the fragment damage field of non rotating axisymmetric charge,the fragment flying state of rotating non axisymmetric charge warhead after rotating at any angle is simulated and simulated by MATLAB.Finally,the initiation delay time and rotation angle corresponding to the maximum damage efficiency of the rotating directional warhead are calculated,and the specific calculation method of the response speed range of the rotating mechanism is given,which provides an important theoretical basis for the fuze warhead coordination design of the rotating directional warhead.
