Since the study on vibration has played an important role in electrical power generation

the achievements about vibration study on turbo-generator shaft system are summarized in recent years

and the development trend was predicted in this research area.In recent years

the general research interests are focused on the rotor pre-balancing

gradual rotor bend treatment

torsional interaction of the units with power systems

anti rotary steam sealing

spring vibration-isolation foundation

cracked rotor

rubbing vibration caused by bearing oil carbonization

and so on.In the future

the hotspots of vibration study on turbo-generator shaft system will focus on the steam-flow exciting vibration sources

spring vibration-isolation foundation dynamic optimization

complex structure vibration treatment and subsynchronous resonance.
