针对拖体回收至母船过程中由于船舶激励、水动力扰动、收放装置和脐带缆运动产生的复杂耦合效应，从而影响拖体回收安全的问题，基于OrcaFlex软件建立拖曳回收系统的动力学分析简化模型，对不同状态下拖曳回收系统产生的动态响应进行研究。结果表明，1.25 m波高波浪的作用下，以较低速度回收时，拖体在穿越波浪区的过程中因摆动会造成底部接触水面，脐带缆会出现突然负载和松弛的现象，但在海水阻尼作用下会减小拖体的摆动角度和水平位移。绞车的突然停止会使脐带缆张力发生显著波动，且会出现张力峰值，以较低的绞车速度用于回收有利于降低脐带缆最大张力。斜浪状态下整个拖曳回收系统的响应值最大，除横浪状态下，船舶的升沉运动往往在尾部偏大，此时在船舶侧部回收拖体较为安全。
In view of the problem that the towed body is recovered to the mother ship due to the complex coupling effect of ship excitation, hydrodynamic disturbance, retracting and releasing device and umbilical cable movement, which affects the safety of towed body recovery. Based on the OrcaFlex software, this paper establishes a simplified dynamic analysis model of the towed recovery system, and studies the dynamic response of the towed recovery system under different states. The results show that: under the action of 1.25 m wave height waves, when recovering at a lower speed, the towed body will cause the bottom to contact the water surface due to swinging during the process of crossing the wave area, and the umbilical cable will experience sudden load and relaxation, but the swing angle and horizontal displacement of the towed body will be reduced under the damping of seawater. The sudden stop of the winch will cause the umbilical cable tension to fluctuate significantly, and there will be a tension peak. Recovery at a lower winch speed is conducive to reducing the maximum tension of the umbilical cable. The response value of the entire towed recovery system is the largest in the oblique wave state. Except in the transverse wave state, the heave movement of the ship is often larger at the tail. At this time, it is safer to recover the towed body from the side of the ship.
