摘　　要：为分析海上火箭回收过程中,船舶在火箭冲击载荷、锚泊力及波浪力耦合作用下的运动响应问题,基于有限体积法在时域计算火箭回落过程中甲板受到燃气射流冲击载荷的时历曲线。之后使用耦合算法将冲击载荷模型与船舶运动相结合,实现回收船舶动力耦合分析计算模型的建立,并在此基础上重点探讨沿船长及船宽分布的不同落点对船舶横摇、纵摇及垂荡运动的影响。得出火箭落点偏心距离的增加会增大船舶运动幅值的结论。部分结果可为海上火箭回收姿态调控提供参考数据。In order to analyze the motion response of ship under the coupling action of rocket impact load,mooring force and wave force in the process of marine rocket recovery,Based on the FVM,the time history curve of the impact load of gas jet on the deck during marine rocket recovery is calculated in time domain.Then,the coupling algorithm is used to combine the impact load model with the platform motion and establish the dynamic coupling analysis of the recovery ship.Based on this,the influence of different landing points along the length and width of the ship on the ship motion is discussed.It is concluded that the increase of eccentric distance of rocket landing point will increase the amplitude of ship motion.Some results can provide data for the attitude control of rocket recovery at sea.
