A vibration monitoring system for high-speed rotating blades of turbine using tip-timing sensors is introduced.The tip-timing sensors based on the principle of reflective fiber can collect tip-timing signals with higher performance.Together with followed optical-electrical transform

data collection and analysis

the real-time vibration detection for high-speed rotating turbine blades is realized by this system.As a result the system has worked best at the real-time experiment on high-speed emulational rotor.The analyzed result including the asynchronous vibration order and frequency by strain gauge are almost completed coherence with the ones by the system.It improves the performance of system for the successful appliance in real-time measurement for compressor blades.
