摘　　要：海上火箭发射船在海洋环境载荷与发射冲击载荷作用下将发生复杂的非线性运动响应,对火箭发射的安全性有着至关重要的影响。本文基于三维势流理论研究不同海况风浪与冲击载荷作用下某海上火箭发射船的运动响应特性,并分析船舶有无动力定位系统、发射点火时间的选择等因素对发射船运动特性的影响。结果表明:发射冲击载荷对船舶的纵摇运动影响较大,尤其是在风浪方向和船舶方向平行时,纵摇角较大;动力定位系统的存在会增加发射船的横摇角度;发射点火时间选择在发射船纵摇运动即将达到极值并折返的时刻,可减小发射船纵摇运动对火箭起飞姿态的影响。A sea-launching ship will have complex nonlinear motion response under the environmental loads and launch impact load,which has a vital effect on the safety of rocket launching process.Based on the threedimensional potential flow theory,this paper focuses on the motion responses of a sea-launching ship under the action of wind,waves,and impact loads in different sea states.And the effects of the dynamic position system and the launch ignition time on the motion of the launch ship were investigated.The results show that the launch impact load has a great influence on the pitch motion of the ship,especially when the wind/wave direction is parallel to the ship direction.The existence of dynamic position system will increase the roll of the launch ship.And the launch ignition time can be selected at the moment when the pitch motion of the launch ship is about to reach the extreme point,so as to reduce the impact of the launch ship's motion on the rocket attitude during taking-off.
