摘　　要：在潜射导弹出筒姿态控制问题的研究中,潜艇的牵连运动和流体力的法相作用影响潜射弹道导弹出筒弹道和运动姿态。为了准确分析潜艇运动和流体力对导弹出筒段运动的影响,根据导弹受力的变化和运动姿态的不同,将导弹出筒过程细分为出筒段和过渡段,并分别建立了相应的数学模型。为了模拟真实环境,以波浪平均理论为基础,将浪流拟合为整体进行了法相流体力的分析。通过仿真计算,得出了导弹在出筒过程中俯仰角和俯仰角速度的变化规律,以及潜艇运动对导弹出筒过程运动姿态的影响规律,仿真结果表明,所建立的模型和计算方法可行,可为研究潜射弹道导弹水下发射技术提供参考和依据。The connected motion of the submarine and the fluid normal force is the key factor to the ballistic and motion attitude of the submarine -launched ballistic missile （SLBM）. To analyze the effect of the connected motion of the submarine and the normal fluid force accurately, considering the variation of the force and the motion attitude, the process was divided into barrel section and transition, and the mathematical models of missile motion were established. To simulate the real environment, basing on the averaging theory of the ocean wave, the current and the wave were considered as a whole factor to analyze the normal force. By simulation, it makes a conclusion about the variation of the pitch angle and pitch rate of missile during outlet of tube, and about the impact on the motion of submarine to missile motion attitude. The simulation result is very close to the real data, which indicates that our model and arithmetic are feasible. The proposed model and the arithmetic can provide a reference and basis for studying the underwater launch technology of SLBM.
