高速自旋导弹直接力控制稳定性研究

Research on Direct Force Control Stability of High-Speed Spinning Missile

研究了作用在质心前部的直接力对于旋转导弹稳定性的影响,建立了直接力作用下旋转导弹的运动模型。基于劳斯稳定判据,给出了使旋转导弹章动稳定和进动稳定的直接力范围的判断方法。仿真结果表明,即使弹体是稳定的,在不同大小的直接力的作用下也会使弹体运动产生章动或者进动,此方法对于直接力在旋转导弹的应用有重要意义。

The influence of direct force to the stability of spinning missile is studied. The mathematic model of spinning missile under the effect of direct force is established ; a method to calculate the range of direct force which can keep the precession and nutation movements stable is given based on Routh stabili- ty criteria. The simulation indicates that the introduction of direct force would lead to precession or nuta- tion movements even the missile is stable, the method is of great significance to the application of direct force to spinning missile.
