摘　　要：潜载导弹采用运载器水下垂直发射时,由于海洋力学环境的复杂性,运载器水弹道会受到海流等多种因素的影响;为了保证发射平台的安全性,运载器应采用规避弹道,同时考虑海流的影响,运用四元数法建立了运载器的空间动力学和运动学数学模型,结合海流数学模型在matlab环境中仿真分析了不同海流影响下运载器在出水时刻的姿态以及水弹道变化趋势;仿真结果表明在进行水下垂直发射时,不同流向和不同强度的海流对运载器水弹道及出水时刻的姿态角的影响各不相同,某些海流的影响甚至是颠覆性的。Due to the complexity of seawater mechanical environment, the trajectory of missile carrier which is vertical submarine launched is affected by many factors. Considering the safety of launched--platform and the influence of seawater, the trajectory of carrier is evasion trajectory and the kinematics model and the dynamics model is established by quaternion. Combining with the mathematical model of seawater, the motion and attitude angle are simulated in different sea conditions. It shows that the different strength and direction have dif- ferent impact on the evasion trajectory and attitude angle, even in some conditions the impacts are subversive.
