摘要	为了对风力发电机在地震-风力作用下的受力情况进行仿真计算,采用多柔体系统动力学理论建立了风力发电机结构动力学分析模型,并在FORTRAN下编程实现;采用动态入流理论进行气动载荷计算,用Euro code 8生成地震谱。以某企业开发的大型风力机为对象,应用该方法,首先进行了模态分析和地震载荷谱计算,同权威计算软件GH Bladed计算结果的比较表明,建立的计算模型正确可行;然后,对该风力机在地震-风力联合作用下的载荷进行了计算,结果显示,此时风力机所受载荷比正常情况下高出许多。
其他摘要	To calculate the loads on wind turbine subjected to earthquake and wind, a structural dynamic model of offshore wind turbine was established based on flexible multi--body dynamics theory and the model was programmed in FORTRAN;the aerodynamic load was calculated based on the dynamic inflow theory and earthquake spectrum was calculated by the Euro code 8. A wind turbine was chosen as study object, the modal analysis and calculation of earthquake spectrum were done by the method. The calculation results are similar to those calculated by GH Bladed which was an authoritative software of wind power, as a result, the correctness and feasibility of the method were verified. Moreover, the loads on wind turbine subjected to earthquake and wind were calculated by the method and the results show that the loads by earthquake and wind are much higher than those at normal conditions.
