摘　　要：针对汽轮机转子弯曲引起振动超标的问题,介绍转子弯曲引起振动的机理,探讨转子通过动平衡抑制振动的可行性,分析动平衡校正200 MW机组高压转子与660 MW机组高中压转子弯曲的过程和结果,由分析结果可知动平衡校正对轻微弯曲的转子效果明显。In view of ultra-standard vibration by turbine rotor bend of several turbines, this paper introduces the mechanism of vibration by rotor bend, and including the feasibility that dynamic balance can retain vibration, analyzes the dynamic balance process and result of 200 MW unit high voltage bend rotor and 660 MW unit high ＆ middle voltage rotor,gets the conclusion that dynamic balance emendation can repair light turbine rotor bend.
