【摘要】 本研究采用时域耦合分析方法对浮式风机系统进行全耦合运动响应分析。水动力分析模块基于势流理论,采用自由面GREEN函数法计算浮体频域水动力系数,采用间接时域法将结果转换到时域;根据锚泊线理论,采用非线性的三维有限元方法分析系泊系统挠性部件;风载荷通过CFD方法来模拟。在此基础上,针对Spar型浮式风机及其系泊系统进行理论计算,给出平台的水动力系数以及在不规则波和定常风以及脉动风下的浮体运动响应和系泊缆索张力响应。该数值模型的计算结果可为风机和系泊系统的设计提供一定的参考依据。更多还原

【Abstract】 This paper calculates the coupled motion response of floating wind turbine system in time domain.The hydrodynamic analysis of platform is based on potential flow theory which uses free surface Green’s function to calculate the hydrodynamic parameters in frequency domain,then the results are transformed into time domain.The analysis of mooring system is based on anchoring line theory which uses non-linear 3-dimensional finite element method.The wind loads are simulated by CFD method.Then the motion and tension response analysis of a Spar type floating wind turbine system is carried out under the irregular wave and steady/pulsating wind environment condition.This numerical model would be helpful in floating wind turbine platform and mooring system designing.更多还原
