无人平台导弹行进间发射仿真分析

针对行进间导弹发射扰动量过大问题,对无人平台导弹行进间发射开展动力学仿真计算.通过分析导致行进间发射扰动产生的主要原因,建立武器站的刚柔耦合动力学仿真模型,将发动机推力和伺服机构运动实测数据作为仿真输入,配合动力学模型计算弹体扰动值.仿真结果表明:改进后的火控流程可实现导弹行进间的可靠发射,发射门限应根据弹体抗扰动能力选取.该研究可为导弹行进间发射流程制定和门限选取提供参考依据.

Simulation Analysis of Unmanned Platform Missile Launching on the Move

Aiming at the problem of excessive launching disturbance of missile launching on the move, the dynamicsimulation of missile launching from unmanned platform is carried out. By analyzing the main causes of the launchingdisturbance on the move, the rigid-flexible coupling dynamic simulation model of the weapon station was established, usingthe measured data of engine thrust and servo mechanism movement as simulation input, and calculate the disturbance valueof the projectile with the dynamic model. The calculation results show that the improved fire control process can achievethe reliable launching of missile on the move, the launching threshold should be selected according to the anti-disturbanceability of the missile. The research can provide a reference for drawing up missile launching process and the selection oflaunching threshold.
