高精度发电汽轮机叶片振动检测系统的研究

Research on high precision power turbine blade vibration detection system

利用高速光电传感器和光导纤维,设计了一种通过测量两个相邻叶片经过同一个光电传感器的时间差的变化,来检测叶片的振动的汽轮机叶片检测系统。与现有的检测方式相比,提高了测量的精度,并降低了系统成本。

This paper develops the turbine blade inspection system, by measuring the difference of the time of two adjacent blades passing by the same photoelectric sensor through high-speed photoelectric sensors and fiber-optics, Compared with the existing detection mode, the proposed method has more measurement accuracy and lower system cost.
