Turbine Rotor Tooth Head and Stress Analysis of Wedge

Abstract:

The turbine generator rotor and the wedge is an important part of the turbogenerator. In order to ensure the stability and reliability of the steam turbine during operation, it needs to calculate and analyze the strength of the generator rotor and the wedge. In this paper, we did the study of the turbine generator rotor and the strength of the wedge by finite element analysis. by using ANSYS software, when in operating speed and speeding, we compared to the results of the calculation of plane and solid elements, and found that the safety factor of the plane was lower. Based on the results of two calculations, we got the generator rotor structure modification and optimization of the structural design, which improve the strength of the generator rotor tooth head and wedge.
