摘要
研究球形波浪浮标风、浪、流作用下的运动响应和系泊张力。利用SESAM软件建立球型浮标有限元模型。采用三维势流理论计算波浪力,得到一系列规则波作用下,不同水深时球形浮标的运动响应。同时计算球形浮标在随机波浪的作用下的时域运动响应。经过计算分析,得到了浮标的幅频响应以及随机波作用下的运动特点,给出了不同水深和波高下系泊锚链的张力。
The motion responses of the spherical wave buoy and the tension of the mooring line were investigated under the wind, wave, and the flow. The finite element model of a spherical buoy was set up by SESAM. The theory of three-dimensional potential flow was used to calculate the wave force, and the dynamic responses of the spherical buoy were also calculated in different water depths under a series of regular waves. Then the motion responses of the spherical buoy were calculated under random wave in time domain. After being calculated and researched, the RAOs of the buoy and the motion characteristics of buoy in random waves were obtained. Then the tensions of the mooring line were presented in different water-depths and wave heights.
