摘　　要："干"发射潜射导弹运载器在出水后尾部分离体的运动对潜射导弹发射安全性至关重要。针对分离体的回落砸艇问题,为了研究分离体的下沉过程,减小砸艇概率,建立了潜射导弹运载器尾部分离体的运动数学模型,以弹器分离前的姿态为分离体的初始参数,在Matlab框架下对分离体水下运动弹道进行了仿真,分析了尾部段分离体在水中的下落过程,获得了尾部段分离体姿态角及角速度等参数的变化规律,得出了尾部分离体在水下的运动规律。结果表明,尾部分离体运动的初始阶段为不稳定状态,分离体的初始运动姿态对其弹道分布有很大影响。研究结果可以对分离体落点进行有效的预估,也可作为相关研究工作的参考。The movement of tail separation section is very important to the safety of submarine - launched missile launch after the ＂Dry＂ launched submarine - launched missile carrier exceeding water. In order to study the possibil- ity of hitting the submarine of the separation section and the sinking process of the separation section, and to reduce the probability of hitting the submarine, the mathematical model of tail separation section of submarine - launched missile carrier＇s movement was established. The initial parameters were based on the posture when the missile and carrier were separated from each other. The author simulated the underwater movement trajectory of the separation section under the frame of Matlab, analyzed the sinking process of the tail separation section in water, and received the transformation rule of the body posture angle and angular velocity and such parameters of the tail section. Results show that the initial phase of the tail separation section movement is unstable, and the initial movement gesture of separation section has a great influence on its trajectory. The results of this paper can effectively predict the wherea- bouts of 1 the tail sectionocation, and it also can be the reference of such safety research.
