潜艇在水下发射导弹瞬间受到巨大的发射反冲力和复杂的水动力作用,平衡状态受到破坏.而连续发射又要求潜艇必须在规定时间内恢复到发射导弹允许的深度和姿态,这对潜艇的操纵控制提出了很高要求.在分析导弹潜艇发射阶段受到的静力、艇体水动力和复杂激变力的基础上,结合潜艇空间运动方程,建立用于仿真的潜艇水下发射导弹操纵运动数学模型.在此基础上,编制潜艇水下发射导弹仿真试验平台,分别对潜艇水下导弹单独发射和导弹齐射时的运动过程进行仿真.通过大量的仿真分析,对潜艇水下发射导弹阶段特别是导弹齐射时可能采用的操纵方式作了定性探索.%The balanced state of the sbumarine would be destroied by the huge recoil force and the complicated hydrodynamic force when it launchs ballistic missile underwater.However,the submarine must return to the depth and the attitude that allowed the missile launched,if we want to launch missiles in succession,which makes very hard requests for the submarine maneuver and controll.Based on the analysis of hydrostatical force,hydrodynamic force and reaction of projection while the submarine is projecting ballistic missile,this thesis combines with the submarine space motion equations and make up of the submarine projecting ballistic missile underwater controlling motion model for simulation.Then it compiles the testing platform for the simulation of submarine projecting ballistic missile underwater,and simulats the motor process of submarine ballistic missile sangle launching and battery launching underwater.By large numbers of simulation,this thesis gets qualitative searching of the probable maneuver when the submarine launchs ballistic missile underwater,especially ballistic missile battery launching.
