摘　　要：建立了脉冲修正弹在脉冲作用下的攻角运动方程,分析了脉冲作用对其特解的影响。利用脉冲修正弹六自由度仿真模型,通过仿真分析了脉冲作用力大小以及其轴向、径向偏心对弹的攻角运动和转速的影响。分析结果对弹道修正方案的设计具有一定意义。The angular motion model of the terminal correct projectile forced by impulse corrective force was built, and the influence of impulse corrective force on the equation of angle of attack and its special solution was analyzed. On the basis of simulation model, the influence of impulse forces and moments on flight stability was analyzed. The conclusion can be referred for impulse correct projectile design.
