【摘要】 基于一台5 MW风力发电机组的实际数据,采用我国地震反应谱,进行有限元反应谱分析。并分别采用日本风电规范、IEC标准及相关文献的计算方法对该5 MW风力发电机组塔架剪力、弯矩进行计算,通过与有限元计算结果对比,分析各公式的适用性,可为我国地震环境下的风力发电机组抗震计算提供有益参考。更多还原

【Abstract】 Based on a 5 MW wind turbine,the finite element response spectrum analysis according to Chinese response spectrum was carried out.Japanese wind turbine specification,the IEC standard and the method of corresponding paper were used to calculate the tower shear and moment.By comparison with the finite element method,the applicability of these methods was analyzed,which can provide a useful reference for the seismic calculation of wind turbines in China.更多还原
