Abstract_Chinese:新型全潜式浮式风机具有可在船坞中建造、整机一体化浮运拖航到安装区域的优点, 从而减少了海上施工过程中大型吊装机械的使用.但是全潜式浮式风机作为一种高耸结构, 在拖航过程中受到的环境荷载倾覆力矩较大, 需要对拖航浮运过程中的稳性进行分析以保证施工过程的安全.本文基于多体动力学方法, 建立了拖船-拖缆绳-全潜式浮式风机整个拖航系统的动力学模型, 研究了拖航过程中风、波浪、海流3种环境影响因素对全潜式浮式风机运动响应的影响.结果表明, 在选取的拖航工况中全潜式浮式风机拖航横摇和纵摇均小于2°, 垂荡位移小于1.3 m; 浮式风机基础拖航纵摇主要受风和波浪影响较大, 而横摇和垂荡受波浪影响较为明显; 在遭遇较大横浪时, 应尽量调整拖航行进方向与波浪方向平行.
Abstract_English:The novel submersible platform for floating wind turbine can be constructed near quayside and then wet towed to the installation site as a unit,which will consequently reduce the use of heavy cranes. However,as a high-rise structure,the submersible floating wind turbine will sustain large overturning moments induced by wind,wave and current. In order to study the stability of floating wind turbine in towing condition,the numerical model of the entire towing system of tugboat-towline-submersible floating wind turbine was established based on mutibody dynamics. The environmental effects on the towing stability of floating wind turbine were investigated. Results show that the roll and pitch of the submersible floating platform are less than 2°,and the heave is less than 1 m. The pitch of the floating wind turbine is mainly governed by wind and wave,and the roll and heave are mainly governed by wave. In addition,when the towing system encounters beam sea,the tow direction is proposed to be parallel with the wave direction.
