Abstract: The forces on submarine are complicated and vary intensely when launching missile vertically, including the reaction force applied by the missile, the negative pressure area produced by the overflow of high pressure gas, the weightless and overweight brought by missile ejection and seawater flood into the launch tube. In actual launching process, the magnitude and characteristic of the intensive forces have randomness, and become uncertain factors varying within a certain range. The simulation model of submarine during missile launching process is established based on the standard equations of motion for submarine simulation, and the launching process and control of submarine motion affected by uncertain factors are analyzed through numerical simulation and computation results.

1.1 导弹筒均压

1.2 开发射筒盖

t2为等待点火时间，打开筒盖时，筒盖如同稳定翼，改变了潜艇的流体动力特性，干扰航行潜艇的航向和姿态。在进行实际分析时，认为发射筒盖从打开到关闭的时间较短，且产生的扰动力有限，从而忽略这部分因素的影响。

1.3 点火和导弹出筒

1.4 导弹筒进水及吹除瞬时补重水舱的水

 P = \left\{ {\begin{aligned}&{{v_1} \cdot t \text{，} \;\;\;\;\;\;\;\;\;\;\;\;\;{\text{当}}0 < t \leqslant {T_1}}\text{，}\\&{{P_1} + {v_2} \cdot t \text{，}\;\;\;\; {\text{当}}{T_1} < t \leqslant {T_2}}\text{。}\end{aligned}} \right. (1)

3 结　语

1）导弹点火出筒产生的发射反力尽管很大，但作用时间很短，对潜艇运动状态的影响能够通过操舵和均衡很快消除。

2）灌水模型随机因素中，欠注水量和第1阶段进水量对挽回控制的影响最为显著，而第1阶段进水时间对齐射过程中潜艇运动状态的控制影响不明显。

3）补重误差造成的剩余静载力∆F将对潜艇运动产生持续的影响，尤其是多枚导弹齐射或组射时，累积的剩余静载力若不能得到及时均衡和消除，将使潜艇的运动参数最终无法满足发射条件。
