摘要
根据导弹运载器外型设计分析其近水面航行的稳定性问题,在导弹运载器水下六自由度运动模型建立方法的基础上,利用Matlab对运载器在大深度发射情况下的控制方案及水中运行弹道进行了数学仿真研究,利用Simulink模块对运载器近水面航行的稳定性进行了分析.数学仿真和稳定性分析结果表明导弹运载器在近水面航行时具有较强的抗纵向扰动能力,运动是稳定的.该研究在运载器的弹道控制和稳定性设计方面具有实际意义.
According to the shape of missile capsule, the stability of missile capsule moving near free water surface was analyzed. Based on the modeling method of capsule in 6 degrees of freedom, the control plan and the trajectory of missile capsule launched in deep water were simulated with the use of Matlab. The stability of capsule moving near free water surface was studied with Simulink mod el. The results of mathematical simulation and stability analysis show that the missile capsule has good performance of anti-longitude disturbance when navigating near water surface, and the motion is stable. The research is useful for trajectory control and stability design of capsule.
