摘要: 为研究海洋中不同的水流形状模型对多场耦合下的系泊系统的影响,以系泊系统为主要研究对象,采用集中质量法、静力分析法以及离散迭代法等对单点系泊系统在风、浪、流3种载荷的共同方向作用下进行建模与计算。通过改变不同水流形状模型的参数以及水深环境因素来研究系泊系统的整体游动区域以及浮筒的淹没程度。结果表明,曲线形状下的水流模型比线性形状下的水流模型对系泊系统的游动区域影响大,同时随着环境因素水深的增加,二者对系泊系统游动区域范围的影响程度均加深;水流也间接影响浮筒的淹没高度,曲线形状模型下的水流模型对浮筒的影响大于线性形状下的水流模型。

Abstract: In order to study the influence of different flow shape models on the mooring system of wave power generation equipment in the ocean, the mooring system is taken as the main research object. The lumped mass method, static analysis method and discrete iteration method are used to analyze and calculate the single point mooring system under the common direction of wind, wave and current loads. The overall swimming area of the mooring system and the submergence degree of the buoy were studied by changing the parameters of different flow shape models and the environmental factors of water depth. The results show that the flow model with curve shape has a greater influence on the swimming area of the mooring system than that of the flow model with linear shape. At the same time, with the increase of water depth of environmental factors, both of them have a deeper influence on the swimming area of the mooring system. Water flow also indirectly affects the submerged height of the buoy, and the influence of the curve model on the buoy is greater than that of the linear model
