摘要
针对目前海洋工程中弱连接双浮体系统约束较少导致的结构运动响应过大的问题,基于"一机一储"式结构概念,提出一种具有多约束的海上漂浮式风力机耦合氢储能双浮动结构.采用Ansys软件对一般海况下多约束双浮动结构的动力响应特性进行仿真分析,结果表明:耦合氢储能装置的风储双浮动结构在纵荡、纵摇和垂荡等3个主自由度方向运动响应较小;氢储能单元垂荡最大运动幅值仅为储能单元高度的7.21％.在一般海况下具有多约束的风力机耦合氢储能双浮动结构具有优良的运动性能.
Abstract
Aimed at the problem of excessive structural motion response caused by less constraints of weakly connected double floating body system in marine engineering,a multi-constrained offshore floating wind turbine coupled with hydrogen energy storage double floating structure is proposed based on the concept of"one machine,one storage"structure.The dynamic response characteristics of the multi-constrained double floating structure under general sea conditions are simulated and analyzed by Ansys software.The results show that:the wind-storage double floating structure coupled with hydrogen energy storage device is of small motion response in the three main degrees of freedom of surge,pitch and heave;the maximal heave motion amplitude of the hydrogen energy storage unit is only 7.21% of the height of the energy storage unit.The wind turbine coupled hydrogen energy storage double floating structure with multiple constraints under general sea conditions is of excellent motion performance.
