地震作用下的风电机组振动仿真分析

摘要
应用基于多柔体动力学的联合仿真技术对地震作用下的风力发电机振动响应进行了研究。首先采用GDW理论进行风力机气动载荷计算分析,在Fortran下建立风力发电"叶轮—机舱—塔架"整机的多柔体系统动力学模型,将该系统模型转化为ADAMS分析模型。然后通过动态链接文件和根据Eurocode8编写的地震载荷谱,在ADAMS中进行地震作用下的风力机系统联合仿真。仿真数据同Bladed软件结果比较表明,该联合仿真方法可较好的模拟风力机在地震作用下的振动响应。该文为研究地震对风力发电机的影响进行了一次有益的探索。
The vibration response of wind turbine under seismic load was analyzed by simulation technology based on multi flexible body dynamics.Firstly the aerodynamic load of wind turbine was calculated by applying GDW theory.The multi flexible body dynamics model for "rotor-nacelle-tower" of wind turbine was programmed in Fortran.Then wind turbine under the action of earthquake was co-simulated in the ADAMS through the dynamic link files and the compiled seismic load spectrum base on Eurocode8.The results compared with Bladed simulation results show that the method is excellent to simulate the vibration response under earthquake.The research work presents a new way for studying the impact of earthquakes on the wind turbine.
