摘　　要：针对脉冲末修弹药技术中冲推器参数选择缺乏理论依据的问题,提出了基于蒙特-卡洛法的冲推器数量与冲量优化方法。该方法对冲推器数量和冲量配置的大样本空间中的每一种样本进行100次弹道仿真,统计每种样本的系统CEP,从而选择最优冲推器数量与冲量配置。仿真结果表明:通过优化的冲推器数量与冲量使系统具有最优的CEP;更为重要的是,通过仿真得到的冲推器数量、推冲冲量大小与系统CEP所对应的仿真曲线,对实际工作中根据所期望的CEP选择冲推器推冲冲量具有重要的参考价值,有利于系统的结构设计。Parameter choosing in impulse jets is short of positive method support. To solve this problem, a method of number and impulse optimization for pulse jets is put forward based on Monte-carlo simulation method. The method simulates each sample in all allocations of number and impulse for 100 times based on six-degree ballistic trajectory model,and then calculates the CEP of each sample to ensure the optimal number and impulse of pulse jets. The simulation results show that the system performs better accuracy with optimized parameters; furthermore,according to the expected CEP, the simulated CEP curve can be important reference for impulse chosen and configuration design of ammunition system.
