锁紧装置对导弹出筒振动影响研究

Study on Influence of Lock Device on Disturbance of VLS

研究导弹垂直发射装置中导向轨对导弹出筒时状态影响问题,并对导向轨进行改进设计。为了能够准确有效地获得导向轨作用力对导弹出筒状态影响规律,将接触碰撞模型引入导向轨和导弹接触区域间隙中,采用拉格朗日运动学方程,建立导弹的垂直发射动力学模型,计算导弹发射过程中振动特性曲线;通过分析发现,导弹发射筒与导向轨边界约束作用是影响导弹出筒口振动的重要因素。为了降低出筒时的振动,提高导弹出筒平稳性,增加锁紧装置设计。通过对比有无锁紧装置系统响应,表明锁紧装置对吸收导弹发射时冲击振动,减小导弹发射振动幅值有积极作用,为提高导弹出筒时的平稳性提供了科学依据。

In order to study the influence of the lock device in missile Vertical Launching System（VLS）,by introducing the contact stress,we constructed the dynamic model based on Lagrange equation. The contact between launching canister and launching shelf was well considered. The simulation results agree with theory,which show that the simulation model is reliable. By contrasting the response of the system with and without the lock device,the results show that the lock device can reduce the system disturbance and improve the launching status.
