Fault Diagnoses Technology of Broken-Blade Propeller Induced Shaft Vibration

Abstract:

The broken-blade propeller induced centrifugal force and hydrodynamic lateral component force will cause the whirling vibration of the shaft system while one of the propeller blades breaks at different positions. Such whirling vibration is investigated in this paper, and the time domain waveform is obtained through using the finite element method. The frequency domain vibration is then calculated by applying Fourier transformation on its time domain waveform. According to the respond results of both time domain and frequency domain, the fault diagnoses technology of shaft vibration is proposed.
