The turbine end of the condenser stator end winding was taken as a research object in this paper.A three dimensional finite element model of the stator end winding was established.Firstly,the periodical variation of electromagnetic force density in the stator end winding underrated load was obtained by numerical simulation with JMAG software.Secondly,the electromagnetic analysis results were coupled to the structural model for transient dynamic response analysis by ANSYS software.Finally,the dynamic response curve and spectrum structure of the stator end winding with time were obtained.The comparison demonstrates a high level of agreement between the numerical simulation and experimental results,which has proved the reliability and accuracy of the simulation analysis method.The conclusion can help to guide the optimization design of the stator end winding structure for the turbine generator.
