摘要 动静碰摩是汽轮发电机组经常发生的故障。深入研究碰摩振动发生、发展的机理,正确诊断并及时报警,提出处理措施,对机组的安全至关重要。从理论、实验研究和现场故障分析、排除和总结两个方面,对近些年来,国内外特别是国内在这两方面的研究结果和现状作一简要总结。 Rub events take place frequently in turbine machinery. Investigation on the mechanism of rubs is very important to diagnosis in time, to prevent the machinery from further severe failures. The recent studies in the respect, both theoreti- cal ones and practical ones, are summarized in this paper.
