Vibration Characteristic Analysis of Hoist Cage Excited by Steelwork Defects
Due to steelwork defects, there is undesired vibration of hoist cage in operation which will influence safety of hoist system. In this paper, 6 degrees of freedom vibration model of hoist cage excited by steelwork defects was established first. Then horizontal and vertical vibration characteristics under different defects as well as relationship between vibration amplitude and hoist load, defect size and hoisting velocity were analyzed through simulation. Finally, simulation model was verified by experiment.
