【Abstract】 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.更多还原
