Abstract

Abstract:

We designed a fiber grating mechanical vibration monitoring system with fiber Bragg grating sensor. The system realized multiple parameter monitoring and remote transmission of vibration frequency, acceleration, velocity and displacement by fast demodulation of real time vibration signal and could provide complete data analysis and display. Experimental results show that the system can be effectively applied to turbine engine and coal mine vibration monitoring, and can provide software support for the fault diagnosis of a mechanical equipment.

Key words: fiber Bragg grating, vibration monitoring, FFT
