摘　　要：确定火箭弹脱离炮口瞬间的姿态对分析弹道的初始扰动以及落点的散布计算都是非常重要的 .该文建立了舰载火箭炮发射过程中约束期内的火箭弹质心运动方程组模型和半约束期内的火箭弹弹轴转动方程组模型 ,分析了发射过程中舰艇的摇摆运动对火箭弹姿态的影响 .仿真结果表明 ,舰艇摇摆对火箭弹的姿态影响较大 。The attitude of rocket off director is important to analyze the initial perturbation and compute the scatter of splash point. According to the influences of ship rocking, the centroid motion model under restraint by director and the axis tilting model under half restraint of rocket were set up. Based on these models, the influence of ship rocking on the attitude of ship launched rocket during launching was analyzed. The results of simulation show that the influences of ship rocking on the attitude of rocket gun is demonstrable, and the model is of some value.
