ABSTRACT
The development of rotor dynamics research theory and technology and the rapid development of the computer technology provide a reliable guarantee for the dynamics analysis of steam turbine rotor system.[1] The simulation calculation of steam turbine main oil pump rotor system will perform an important instruction function to the stable operation of the steam turbine unit; meanwhile, it is also a powerful supplement for the prototype measurement. Compared with prototype measurement, the computer simulation is more flexible, it can give out the response situation of any part of the shafting, so we can realize the operate situation of rotor system more comprehensive.
