The Study on Structure Vibration Real-Time Monitoring System

Abstract:

On the basis of the review of the present situation and existing problems in structure real-time monitoring system, the paper designs and develops a structure vibration real-time monitoring system. In process of the application, spectral analysis was carried out through fast Fourier transform (FFT) technology, at the same time, the deformation and inherent mode shapes are monitored. In one words, the system realizes synchronously the real-time display of the structural total characteristic, mode shapes, time and frequency signals of key testing points on computer screen. In order to prove the validity of the system, the paper the paper takes a simple-supported beam for an example and receives a satisfying result.
