潜艇在导弹垂直发射过程中所受的激变力十分复杂，包括导弹弹射出筒的发射反力、高压燃气溢出造成的负压区、导弹出筒与海水灌冲发射筒造成的失重与超重等。在实际发射过程中，这些激变力的大小及其时间特性都具有一定的随机性，因而成为在一定范围内变化的不确定因素。结合潜艇空间运动方程，建立潜艇垂直发射导弹过程的仿真模型，根据数值仿真计算结果，分析不确定因素对导弹发射及潜艇状态挽回控制过程的影响。
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.
