Simulation of Converter Torsional Vibration Based on Multi-body Dynamics

Abstract

Abstract: Torsional vibration of large converter is very easy to cause the transmission gear failure. In order to solve large converters' torsional vibration during working, a converter multi-body dynamic analysis model on rigid-flexible coupling method was built by using of multi-body dynamics simulation software RecurDyn and the finite element analysis software ANSYS. And the dynamic simulation study of this model was carried out. The effects of torsional vibration by different parking methods, parking times, the converters' vibration frequency and the amplitude were obtained through the dynamics simulation calculation. The results show that the torsional vibration amplitude of converter can be reduced effectively by increasing the parking time and damp, and also by controlling the speed curve of motors. These results can offer a theory basis in solving the torsional vibration of the converter.

Key words: converter, rigid-flexible coupling, multi-body dynamics, torsional vibration
