缓冲装置对某导弹系统初始扰动的影响研究

摘要

To study the influence of the buffer device on initial disturbances, a coupling multi-body dynamic model of a missile system was built based on the Lagrange equation. The contact between the missile and launch tube was studied as well in this dynamic model. The simulation results agree with the experimental data. The dynamic responses and the initial disturbances were studied by considering the influences of thrust misalignment and clearance. By comparing the responses of system with and without buffer device, the result indicates that the buffer device could reduce the influence induced by initial disturbances.%为研究缓冲装置对导弹系统初始扰动的影响,将接触变形碰撞模型应用于某导弹弹筒间隙中,基于拉格朗日方法建立了安装后坐缓冲装置的导弹发射系统运动耦合的多刚体动力学模型.通过数值仿真得到了系统的动力学响应,结果与实测参数基本一致.通过对比无缓冲装置的系统响应,说明安装后坐缓冲装置能够减小系统初始扰动,对推力偏心和弹筒间隙的影响具有调节作用.
