摘　　要：空空导弹破片战斗部对空中运动目标的单发杀伤概率模型存在不足,精确计算其单发杀伤概率,并对导弹战斗部主要参数进行优化设计,对战斗部的总体设计和提高战斗部效能具有重要意义。在分析战斗机要害部位特性的基础上,根据战斗部对运动目标的杀伤机理,分别建立单枚破片对目标的击穿模型、引燃模型和冲击波杀伤模型;基于所建立的战斗部条件杀伤概率模型,采用多指标单目标粒子群优化算法对战斗部的装填系数、破片数量、单枚破片质量、破片静态飞散角和破片静态飞散方向角五个主要参数进行优化设计。结果表明:优化不仅改善了高密度内埋空空导弹单发杀伤效能,而且减小了战斗部的质量。研究结果可为新型战斗部设计提供参考。The air-to-air missile warhead of air moving target single kill probability model is still inadequate.It is necessary to accurately calculate the single kill probability and optimize design of the main parameters of missile warhead.Based on the vital part analysis of the aircraft,the breakdown model and the ignition model of single fragment,as well as the shock wave damage model to the target are established according to the warhead against moving target.Based on the established single kill probability model,objective particle swarm optimization algorithm is used to optimize the loading coefficient,fragments numbers,fragment mass,static scattering angle,static scattering direction angle.The results indicate that the optimization results not only improves the missile kill probability and its main parameters,but also reduces the mass of the warhead.The results will supply new warhead design with a reference.
