Analysis of Stress and Strain on High pressure steam turbine Steam Turbine shaft due to Mechanical Loading–Review

Abstract

The present study is carried out for a steam turbine shaft. Analysis of stresses and strain for mechanical load on a High pressure steam turbine shaft is done by using FEM analysis. A steam turbine rotor is considered. It carries wheels, bearing journals, and other parts connected to it. The function of steam turbine shaft is to transmit the power to driven mechanism. The blades are grooved to shaft at each stage. The mechanical forces on the steam turbine due the velocity of the steam and various mountings on the steam are studied. The tangential, axial and centrifugal forces on the steam turbine are calculated. The material 30CrMoVsteel is used for the shaft. The properties of material are applied on the software model. Then suitable boundary conditions are applied on the CAD model of shaft and analysis is carried out by using FEM software ANSYS.
