摘　　要：针对近炸引信适时起爆战斗部关系到对目标有效攻击乃至高效毁伤的问题,提出研究引信与战斗部配合的最优关系计算方法。建立引信近炸时战斗部威力数学模型,依据粒子群优化算法分析相关参数之间的关系;利用欧拉距离法对惯性权重进行动态更新,得到改进粒子群优化算法,将其应用于数学模型中,获得引信与战斗部配合威力计算模型。通过仿真实验得出杀伤面积与引信近炸时炸高、弹丸落角的关系,确定引信与战斗部配合最佳威力的条件,计算最大杀伤面积、90%杀伤面积对应区间和对应炸高。结果表明:该方法是可行和有效的,比传统方法计算最大杀伤面积精度更高,比粒子群优化算法收敛速度更快,更能满足靶场试验和实战化射击对计算速度的需求。The timely detonation of warhead with proximity fuze is related to whether it can effectively attack and destroy a target.The optimal coordination relationship of fuze and warhead is proposed.A mathematical model of warhead power is established.The relationship between related parameters is analyzed using the particle swarm optimization algorithm,and the inertia weight is dynamically updated using the Euler distance method.An improved particle swarm optimization algorithm was presented and applied to the mathematical model to obtain the calculation model of warhead power in fuze-warhead coordination.Through simulation experiments,the relationship among lethal area,burst height and falling angle was obtained,the best power conditions for fuze-warfare coordination were determined,and the maximum lethal area,the corresponding interval of 90%lethal area and the corresponding burst height were calculated.The results show that the proposed method has higher calculation accuracy of the maximum lethal area than the traditional method,and has faster convergence speed than the particle swarm optimization algorithm,which can better meet the speed calculation requirements for the range test and tactical fied firing.
