Based on data analysis in both time and frequency domain, characteristics ofbladevibration response at rotating stall and surge condition are introduced.
在对时域和频域数据分析的基础上,论述了旋转失速和喘振状态下叶片振动响应的特征。
2
Exact measurement for the actual vibrationfrequencyof the blade was the focus.
准确地测量叶片实际振动的频率和振幅已成为透平机械的一个重要研究方向。
3
The modification for the natural frequency and the mode ofvibration of blade are needed to treat the fault of steam turbogenerator caused by it's blades.
