摘　　要：本文结合具体案例,对引起水电机组共振和噪声的几种主要因素:尾水管压力脉动、卡门涡列、电磁因素等进行了分析,并对抬机现象和厂房共振进行了研究,最后给出了解决问题的建议。Combining the concrete case, the resonance and noise caused by some main factors： pressure pulsation of tail pipe, Carmen vortex column, electromagnetic factors, were analyzed in this paper, and the shaft-lift phenomenon and resonance of workshop were also studied. At last, some suggestions to solve the problem were given.
