摘要
水下发射潜地弹道导弹时,由于水下环境的复杂性导致导弹的水下弹道要受到多种干扰因素的制约,为分析波浪干扰力对导弹出水运动的影响,针对潜地弹道导弹水下垂直发射方式,运用四元素法建立了潜地弹道导弹出水运动模型,并结合波浪扰动力数学模型在matlab/simulink环境中计算不同海况下导弹所受到的波浪力及导弹的运动姿态。仿真结果表明,波浪在近水面对潜地弹道导弹出水运动的影响不容忽视,波浪对导弹水下弹道及出水姿态的影响,不仅与海况有关,而且还与波浪方向角及初始相位角有关。
Due to the complexity of the underwater condition, the underwater-trajectory of missile is constrained by many factors when launched underwater. In order to analyze the affect of wave force on the exceeding water motion of submarine-to-ground ballistic missile which vertically launched underwater, the exceeding water motion model of submarine-to-ground ballistic is established by means of quaternion. Combined with wave force model, the wave force and the motion of the missile are calculated under different sea condition by matlab/simulink. The result of simulation shows that the affect can not be neglected in the surface of water, and the degree of which relates to the sea condition, the orientation angle and the initial phase of wave.
