摘要

针对近海薄膜式光伏浮岛

利用耦合的欧拉-拉格朗日（CEL）有限元方法进行流固耦合分析。首先通过造波理论和模型试验验证CEL方法的可靠性;之后通过CEL数值模拟

研究薄膜式光伏浮岛在不同条件下的受力特性。研究结果表明：浮管的随浪性影响浮体运动状态和薄膜受力;波浪作用下薄膜应力较大的关键位置有膜-绳连接处、光伏组件间薄膜和光伏组件-薄膜接触点

随着波高的增大

关键位置应力增大

而随着周期的增大

关键位置应力减小;当波高为5 m且发生破碎时

波浪越过浮管直接击打薄膜

导致光伏组件附近薄膜发生破坏。

Abstract

This paper focuses on offshore membrane-based photovoltaic floating islands and conducts fluid-structure interaction analysis using the coupled Eulerian-Lagrange （CEL） finite element method. Firstly

the reliability of the CEL method is verified through wave generation theory and model tests. Subsequently

numerical simulations using the CEL method are conducted to study the stress characteristics of the membrane-based photovoltaic floating island under different conditions. The research results indicate that the wave-following behavior of the floating tubes affects the motion state of the floating body and the stress on the membrane. The key locations where the membrane experiences significant stress due to wave action are at the membrane -rope connection

between the photovoltaic panels

and at the contact points between the photovoltaic modules and the membrane. As the wave height increases

the stress at these key locations also increases

while as the wave period increases

the stress at these key locations decreases. When the wave height is 5m and breaking occurs

the waves strike the membrane directly after overtopping the floating tubes

leading to damage to the membrane near the photovoltaic modules.
