| 摘 要： | 将某类海上自动作业系统简化为带移动负载的浮筒系统,其中负载简化为外径为180mm、约50kg重的柱型体,浮筒为外径533mm的圆筒;初步设计了浮筒系统的主参数。在此基础上,采用频域数值模拟计算,获得了浮筒自由状态下的固有周期和运动响应传递函数(RAO);再采用时域模拟方法,预报了3级海况下(JONSWAP谱)浮筒系统整体的运动响应特性,给出了运动响应幅值、最小干舷高度等特性参数,可为相关装备设计提供技术参考和借鉴。

| Abstract: | Some kind of operation system at sea was simplified to a buoy with a moving payload inside, where the buoy is a floating cylinder with outer diameter of 533mm and the payload a cylinder with outer diameter of 180mm and weight of 50kg. Such a buoy system is designed to operate under the sea state 3 with adequate stability. Its natural cycle in calm water and RAOs of motion in waves are calculated by numerical simulation with frequency domain method. Thereafter, the time history of motion of the buoy system under the sea state 3 was obtained through time domain method, where the JONSWAP wave spectrum was adopted. As results, the amplitudes of buoy''s motion are presented and the buoy''s freeboard recommended. |
