摘要
漂浮式风电平台在波浪中的摇晃运动会导致塔架根部产生很大的弯矩,极大地威胁平台结构安全.同时流体的附连水质量效应对平台塔架结构的动响应有着较为显著的影响,因此充分考虑这种流固耦合效应有利于更加准确地评估平台塔架的结构动响应.采用三维频域线性水弹性方法计算塔架在流体作用下的结构共振频率特征以及各阶模态振动的主坐标响应特性,然后通过弹性模态叠加法获得塔架的弯矩载荷.并结合概率学手段,预报了短期极限海况下塔架弯曲载荷响应,为新一代漂浮式风电平台结构安全性评估和方案设计提供了技术支撑.
Abstract
The swaying motion of floating wind turbine platforms in waves can result in significant bending moments at the base of the tower,posing a significant threat to the structural integrity of the platform.Meanwhile,the added mass effect of the fluid has a significant influence on the dynamic response of the platform tower structure.Therefore,fully considering this fluid-structure interaction effect is conducive to more accurately assessing the structural dynamic response of the platform tower.Using a three-dimensional frequency-domain linear hydroelastic method,the structural resonance frequency characteristics of the tower under fluid action and the principal coordinate response characteristics of each mode of vibration are calculated.Then,the bending moment load of the tower is obtained through modal superposition method.Combined with probabilistic methods,the bending load response of the tower under short-term extreme sea conditions is predicted,providing technical support for the safety assessment and design of next-generation floating wind turbine platform structures.
