摘　　要：为找出引起垂直发射舰载火箭弹出筒姿态初始扰动现象的原因,揭示舰船运动产生惯性过载的规律,分析舰船运动对出筒运动参量的影响。考虑推力偏心、摩擦力和舰船运动,建立出筒过程动力学模型,推导火箭弹随舰船运动产生的惯性过载,并运用龙格-库塔数值方法求解出筒姿态。结果表明,在五级海况下,舰载火箭弹的出筒速度、姿态角和角速度受到舰船运动的不同程度影响,其中偏航角速度和俯仰角速度的变化较大,且出筒速度的仿真结果和实验数据保持一致,验证了动力学模型的正确性。为确保发射精度进一步开展舰载火箭弹出筒姿态控制设计提供了依据。The purpose of this study is to find out the cause of the initial disturbance of the vertical launching of the ship-borne rocket’s ejection attitude,reveal the law of inertial overload caused by ship motion,and analyze the influence of ship motion on the ejection motion parameters.Considering the thrust eccentricity,friction and ship motion,a dynamic model of the ejection process is established,the inertial overload of the rocket with the ship motion is derived,and the Runge-Kutta numerical method is used to solve the ejection posture.The results show that under five-level sea condition,the exit velocity,attitude angle and angular velocity of ship-borne rockets are affected by the motion of the ship to varying degrees.Among them,the yaw rate and pitch rate change greatly.The simulation results of the exit velocity are consistent with the experimental data,which verifies the correctness of the dynamic model.In order to ensure the launch accuracy,this research provides a basis for further development of the ejection attitude control design of ship-borne rockets.
