基于AQWA软件,对无岛礁和有岛礁地形下带系泊系统的单浮体进行了水动力及运动响应的数值模拟并与带岛礁地形模型试验的RAO进行了对比分析.为浮体在实际海洋环境中的施工和运营安全等做出准确预报.研究结果表明,AQWA可以比较准确地模拟岛礁对浮体的绕射和辐射等干扰;由于海底地形变化的影响,波浪将发生折射、绕射、反射等一系列的复杂变化,同时海底倾斜会对系泊缆张力造成影响,从而会影响浮体的运动响应,这种影响主要是浮体低频运动造成的.岛礁地形对单浮体计算模拟岛礁地形下浮体的运动响应结果与水池试验得到的数值对比吻合良好.
Based on the AQWA software, the numerical simulation of the single-buoy with no island reefs and reef-tied moorings has been carried out and compared with the RAO with the island reef terrain model tests. Marine environment, etc. The results show that AQWA can accurately simulate the diffraction and radiation of the floating bodies caused by the reefs, and the waves will be refracted and diffracted due to the influence of the seafloor topographic changes , Reflection and a series of complex changes, while the seabed tilt will affect the mooring line tension, which will affect the floating body’s motion response, this effect is mainly caused by low-frequency movement of the floating body. The results of the motion response of the floating body under the terrain are in good agreement with the values obtained from the pool test.
