摘要
针对海上浮式风机(Floating offshore wind turbines,FOWTs)受到风浪作用会产生六自由度运动,而鲜有关于风机位姿变化对于系统安全及能量利用影响研究的现状,本文对基于6-PSS并联机构的风机运动模拟装置的动力学展开研究。根据风机参数和典型海况,给出了运动模拟装置的运动参数和尺寸参数,建立考虑风载荷和浮动基础运动的风机—运动模拟装置的动力学模型,并采用数值积分法对系统的响应进行分析。基于该模型,研究了风载荷和不同平台运动规律对于运动模拟装置的影响,发现当模拟纵荡或纵摇运动时,滑块驱动力幅值及变化相同或存在一定相似,风载荷改变会影响滑块驱动力幅值及变化周期。
In view of the situation that FOWTs(floating offshore wind turbines)may have six-degree-of-freedom motion under the effect of wind and waves,while few research on the influence of the change of FOWTs’position on the system safety and energy utilization.In this paper,the dynamics of the FOWTs motion simulator based on 6-PSS parallel mechanism is studied.According to the FOWTs parameters and typical sea conditions,the motion parameters and size of the motion simulator were given,and the dynamics model of the FOWTs motion simulator considering wind load and the motion of the floating platform was established.The response of the system was analyzed by numerical integration method.Based on this model,the effects of wind load and different platform motion on the motion simulator were studied,come to the conclusion that driving force of slider has similarity when simulating surge and pitch,and the variation of the wind load will affect the value and period of driving force.
