摘要
采用有限元方法建立了立轴风力机风轮的振动分析模型,分析了离心力对风轮固有频率的影响,并运用此模型对500 kW风力机风轮的振动模态作了仿真分析,得到风力机运行过程中风轮的固有频率与外激励频率之间关系的Campbell图,为立轴风力机结构的振动特性设计提供参考.
This paper uses finite element method to build a vibration analysis model of vertical axis wind turbine （VAWT） and analyzes the influences of centrifugal force on the natural frequencies of turbine. With this model, this paper carries out simulation analysis of vibration mode of a 500KW VAWT and ob- tains the Campbell diagram about the relationship between natural frequencies and excited frequencies during turbine operation, which can offer references for VAWT design of vibration characteristic.
