摘要
针对舰炮制导炮弹射击效力分析中解析法难以给出准确表达式的问题,提出了一种基于过程仿真的制导炮弹射击效力分析方法。对舰炮制导炮弹在飞行过程中的误差因素进行分析;结合其工作特点和原理,建立了制导炮弹外弹道仿真模型;在此基础上利用蒙特卡洛法开展仿真,计算得到误差综合作用下的射击效力并量化分析了弹道风、定位误差、气动系数误差和火箭推力误差对射击效力的影响。结果表明定位误差是影响舰炮制导炮弹射击效力的主要因素,该研究可为舰炮制导炮弹相关技术参数设计和系统精度研究提供参考。
Aiming at the problem of the difficulty of the analytic method in giving an exact expression in analysis of firing effectiveness of the guided projectile of the naval gun,a method of effectiveness analysis of the guided projectile based on process simulation was proposed.An analysis was conducted of the error factors in the course of the flight of the guided shell of the naval gun,with the external trajectory simulation model of the guided projectile established according to its working characteristics and principles.On this basis,Monte Carlo method was used for simulation,with the firing effectiveness under the synthetical effect of error calculated,and with the effects of ballistic wind,positioning error,aerodynamic coefficient error and rocket thrust error on the firing effectiveness quantitatively ana-lyzed.The results show that the main factor affecting the firing effectiveness of the naval gun guided projectile is the positioning error.The research can be used as a reference for the design of related technical parameters and research on system precision for the guided projectile.
