Abstract :
In this paper, 6 degrees of freedom vibration model of hoist cage excited by steelwork faults was established first. Then horizontal and vertical vibration characteristics under local faults and whole faults were simulated through MATLAB, based on which a wavelet singularity method was proposed to process the vibration to determine the position and seriousness of the steelwork faults. Finally, simulation model and the signal processing method were verified by test.
