The mechanism and features of steam flow exciting vibration on steam turbines

as well as analysis of highpressure rotor low frequency vibration resulting from steam flow exciting vibration occurred in recent years on some domestic largescale steam turbines and remedial measures taken in the fields have been presented

summarizing the main causes leading to the said vibration. And countermeasures should be taken for developing high parameters and large capacity units

especially supercritical units

in our country have been suggested.
