摘要：

以海上大型漂浮式风电机组三浮桶式支撑结构为对象，考虑风波联合作用，借助叶素-动量理论和线性波理论，联合风载荷和波浪载荷模型构建了风波联合载荷模型。计算过程中，考虑了风电机组不同的运行工况，依据浮桶直径与波长的比值来确定波浪载荷适用的计算模型（Morison理论与绕射理论）；得到了不同工况、不同环境参数和结构参数条件下的载荷结果，分析了风波载荷的变化特征。

关键词: 漂浮式风电机组, 风波载荷, 叶素-动量理论, 线性波理论

Abstract:

Three-floating-barrel support structure of large scale offshore floating wind turbines was researched herein. Considering the combined action of wind and wave, using the BEM theory and linear wave theory, the wind load model, wave load model, and wind-wave combination load model were built. In calculation process, different operating conditions of wind turbines were considered, the different wave load models,Morison formula and diffraction theory,were selected based on the ratio of floating barrel diameter to wave length. Load calculation results for different operating conditions, environment parameters and structure parameters were obtained, and the load characteristics were analyzed.

Key words: floating wind turbine, wind-wave load, blade element momentum(BEM) theory, linear wave theory
