【摘要】 漂浮式风力机长时间运行将导致平台系泊疲劳磨损，使得其张力值远低于设计值。极端海况下一旦某跟系泊失效，剩余系泊连续断裂的可能性大增。工业标准要求平台在两根系泊失效后不发生倾覆，故对系泊失效后的漂浮式风力机开展动态响应研究具有重要意义。本文以基于Barge平台的5 MW漂浮式风力机为研究对象，利用AQWA与OpenFAST的气动–伺服–结构模块构成联合仿真系统，对比分析平台同一侧两根系泊失效和同一角两根系泊失效两种情况下，平台动态响应及剩余系泊张力的变化。结果表明：同侧两根系泊失效后，平台最大漂移距离增加为原来的两倍；同一角两根系泊失效后，系泊系统出现渐进性失效过程，且失效间隔时间越短，平台动态响应越剧烈。更多还原

【Abstract】 Prolonged operation of a floating wind turbine can result in fatigue wear of the platform mooring,causing its tension value to fall significantly below the design value.In severe sea conditions,failure of one heel mooring increases the likelihood of progressive fracture of the remaining moorings.Industry standards mandate that a platform should not capsize after two mooring failures;therefore,it is crucial to investigate the dynamic response of floating wind turbines following such failures.This study focuses on a 5 MW floating wind turbine based on Barge platform and constructs a joint simulation system using AQWA and OpenFAST’s aero-servo-structural modules to compare and analyze changes in platform dynamic response and residual mooring tension under two root mooring failures on one side or at one corner.The results indicate that maximum drift distance doubles when both root systems fail simultaneously on one side.When both systems fail at one corner,there is progressive failure with more severe platform dynamic responses as failure intervals decrease.更多还原
