摘要
基于时域耦合分析法,建立了母船-深海采矿装备-脐带缆三维非线性水动力学模型,并对布放及回收过程中脐带缆的水动力响应特性进行了数值计算与分析。结果表明,4级海况时,深海采矿装备(水中重10 t)可以在速度0.8 m/s条件下安全布放和回收;在波浪和海流共同作用下,深海采矿装备在布放开始阶段和回收结束阶段都有强烈的振荡和摆幅,可安装防摇止荡装置来降低振荡和摆动。
Based on the time-domain coupling analysis method,a three-dimensional nonlinear hydrodynamic model for mother vessel,deep-sea mining equipment and umbilical cable was established,and numerical calculation and analysis were also conducted for the hydrodynamic response characteristics of umbilical cable during launch and recovery.The results show that deep-sea mining equipment(weighing 10 t in water)can be safely launched and recovered at a speed of 0.8 m/s under condition of sea state 4.Due to the influence of both waves and currents,the deep-sea mining equipment will have strong oscillations and swings at the beginning of launch and at the end of recovery,which can be reduced by installing anti-swaying devices.
