潜地导弹出筒运动仿真

导弹的出筒运动决定了导弹水中运动的初始参数,直接影响导弹的水中弹道。通过建立潜地导弹出筒运动模型,研究导弹在出筒运动中所受到的外力以及在外力作用下导弹出筒参数的变化,分析潜艇的摇摆运动对导弹出筒速度和姿态的影响。仿真计算结果表明:潜艇的摇摆运动对导弹的出筒速度影响很小,对导弹的出筒姿态角影响较大,特别是潜艇的纵摇运动对导弹出筒姿态角的影响比较显著,且潜艇摇摆运动的周期越大,导弹的出筒姿态越接近垂直。

Simulation on the Motion in Tube of a Submarine-to-Ground Missile

The missile motion in tube decides the initial parameters of the missile motion under water, and direct- ly affects the trajectory of missile launched vertically under water. A dynamic model was built to analyze the forces working on the missile during the movement in tube and how the elements of the missile movement changed under the effect of those forces. And it was discussed that how the submarine sway motion affected the outlet velocity and attitude of missile launching from the submarine. The result of simulation showed that the submarine sway motion had less influence on the outlet velocity than that on the outlet attitude. The pitch of submarine had much effect on the outlet attitude of the missile. And the outlet attitude of the missile was clos- er to be vertical with a longer sway period of the submarine.
