Research on FFT and FBG Mechanical Vibration Monitoring System

Abstract:

The vibration sensor signal acquisition and FFT signal processing principle are described in detail, designed a fiber Bragg grating vibration monitoring system. On one hand, the system realized the multi-parameter data acquisition and remote transmission of fiber Bragg grating technology, on the other hand, provide complete data analysis and display functions. The experimental results show the system can be used effectively for turbine engine vibration monitoring, provides software support for subsequent fault diagnosis.
