Study on fault mechanism of shaft hoist steelwork

Some achievements have been made in detecting the vibration faults in shaft hoist steelwork, but very little information is currently available to help study the faults mechanism. The faults during the run-ups stage are different from the faults during even speed stage. This paper deals with the fault mechanism through establishing the vibration model as the conveyance moves in shaft. By simulation we can see different vibrating instances correspond to different steelwork faults, and then we put forward suitable fault diagnosis methods.
