Abstract

Torsional vibration is one of the major problems of the Yangtze-Gorges ship elevator. The cause of the vibration and its suppression method are approached in this paper. To simplify the analysis, a 2 motor-1 shaft (2M-1S) system instead of real 4 motor-4 shaft (4M-4S) system is investigated first and the analysis results are verified by simulation and experiments. Then the (4M-4S) system is analyzed and simulated and the results show that it is reasonable to simplify the system by the (2M-1S) one
