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
