摘要
对弹道修正弹武器系统组成和工作原理进行了研究,建立了脉冲作用力及力矩模型、分析了弹道修正使用的追踪制导律,提出了建立其六自由度弹道模型的方法,利用弹道修正弹六自由度弹道仿真程序对末段修正典型弹道、探测器光轴运动轨迹以及脉冲作用点对脱靶量的影响等进行了仿真,计算结果表明在弹体质心附近使用直接脉冲控制力对末段弹道进行修正可以达到较好效果,采用速度追踪方式能够得到较小的脱靶量。
The makeup of course correction projectile weapon system and its working principle were studied, the models of impulse force and impulse moment were established, the pursuit guidance laws used for course correction were analyzed and the method of establishing 6-DOF trajectory model of course correction projectile was presented. Typical course correction trajectory, orbit of laser detector optical axis and the influence of acting point of impulse force on miss distance were simulated by 6- DOF course correction trajectory simulation program. Simulation results indicate that direct impulse force nearby the mass center can achieve better effect on correcting final trajectory, the miss distance of velocity pursuit guidance law is smaller than that of body pursuit guidance law.
