滚转隔离结构制导火箭弹蒙特卡洛法仿真研究

摘要

Dynamic modeling and Monte Carlo shooting imulation for guided rocket projectile of rotated isolation structure were investigated. Based on the relative motion relation between the two parts of remodelled guided rocket projectile, the center of mass dynamics equations of the guided rocket projectile of rotated isolation structure was established. This article established simulation model of the rocket projectile with Monte Carlo shooting method utilizing Simulink. Three hundred times of simulated shooting for guided rocket projectile were executed in terms of a certain model of rocket projectile by variety of initial disturbances and interference of the gust. It also calculated the sample data variance of the point of fall and the CEP. The simulation results illustrate that the dynamic model is valid and is of the character of high precision attack of remodelled guided rocket projectile.%研究一种滚转隔离结构制导火箭弹动力学建模与蒙特卡洛打靶仿真.根据改造后的制导火箭弹前后两部分的相对运动关系,建立了滚转隔离结构制导火箭弹的质心动力学方程组,并基于Simulink平台建立了蒙特卡洛打靶动态仿真模型.在各种初始干扰和阵风干扰的情况下,进行了300次仿真试验,计算了落点样本数据的均方差和圆概率误差.仿真结果验证了所建模型的正确性,同时也证明了改造后制导火箭弹具有高精度的打击特点.
