摘　　要：由于水下弹道是潜射弹道导弹特有的一段弹道,导弹在垂直向上穿越海水的过程中经历了复杂的环境变化。受海浪等多种环境因素的影响,弹体水中航行阶段俯仰姿态发生急剧变化,严重时可导致发射失败。为了准确掌握海浪对弹体俯仰姿态的影响规律,优化导弹航行姿态,根据动量和动量矩守恒定律建立了导弹水中运动数学模型,将导弹受力进行分解,并以线性波浪理论为基础分析了海浪对弹体的作用形式,利用MATLAB软件仿真计算了不同浪向和浪级条件下导弹俯仰姿态的变化情况。研究结果表明,随着浪级的增高,波浪对导弹运动姿态的影响越发明显,在优化水中弹道设计和实施导弹发射时必须将海浪作为重要影响因素加以考虑。The underwater trajectory is a special section of the submarine＇s vertical launch missile. Due to the in- fluence of various environmental factors, the pitch attitude of projectile has changed dramatically, it can lead to launch failure. In order to accurately grasp the influence of waves on the missile＇s pitch attitude and optimize the atti- tude of missile, according to the conservation law of momentum, a mathematical model of missile water movement is established, and the missile force is decomposed. Based on the linear wave theory, the effects of the waves on the projectile are analyzed. The pitching attitude of missile under different wave conditions is simulated by MATLAB soft- ware. Simulation results show that, with the increase of wave level, the influence of the wave on the missile＇s attitude is more and more obvious. In optimizing the design and implementation of the underwater trajectory, the sea waves must be considered as an important factor.
