Abstract

Aiming at the structural vibration problem of a 600 MW steam turbine generator, the model of its rotor and stator is established by using the finite element theory, and their respective structural characteristics are studied. The results show that the reason for the insufficient stiffness of the generator end cover bearing is the deformation on both sides of the generator stator. The vibration fault was solved by the method of weighting on site.
