摘要
采用试验模态的方法,对轴流风机二级叶片进行模态分析试验,得到二级叶片各阶的模态频率和对应的振型,为叶片振动特性影响的分析提供参考依据。
The experimental modal analysis was carried out on axial-flow fan secondary blade with the method of experimental modal in this paper.The modal frequecny and corresponding vibration mode at any stage of secondary blade were obtained,which had provided referencing basis for analyzing the influnence of blade’s vibration characteristics.
