摘要 针对迫弹的末段弹道修正问题,建立了基于脉冲控制的飞行动力学模型。结合弹道模型,分析了脉冲个数、脉冲力大小、布置位置、弹丸转速、脉冲作用时间等脉冲参数和弹道参数对末段修正能力和弹道特性的影响规律。以某迫弹和给定的脉冲控制修正方案为例,进行了末段弹道仿真计算,得到了关于修正能力的定量仿真结果和末段修正过程中迫弹攻角变化曲线。研究结果表明了末段脉冲控制修正弹道偏差的有效性,也为末段修正迫弹的脉冲控制方案设计提供了一定的理论基础。 In view of the problem of correction of the end of ballistic trajectory of mortar, this paper builds a dynamics model based on impulse control and analyzes the effect of impulse and trajectory parameters on terminal correction ability and trajectory characteristic. The parameters include impulse numbers, forces, location position, rotating speed of pills, working-time of impulse. The paper completes the simulation calculation with the model and arithmetics, draws the curves of attack angle in the correction progress. The result shows that the warp is reduced effectively by the impulse control and that the model and arithmetic are suitable for simulation calculation and analysis under impulse control. This research offers academic reference for impulse control design of terminal correction projectile.
