Abstract
In order to solve problems of large vibration and long-term over-standard of vibration of No.6 and No.7 bear-ings of 330 MW unit in some power plant in operation,finite element modeling was applied for force analysis on beams of basic Ⅳ frame of the steam turbine and its related bearing pedestal.The results indicated that the main reason for abnormal vibration of the bearing was insufficient axial stiffness of the basic Ⅳ frame of the steam turbine.Therefore,a scheme of reinforcing basic Ⅳ frames of bearing pedestals of No.6 and No.7 bearings was proposed.It was proved that this scheme could produce good effects and ensure safe and stable operation of the unit.关键词
