摘要
本文介绍了白山抽水蓄能电站进出水口拦污栅条振动的研究方法和成果,通过测量栅条的激振力频率和结构自振频率,判断栅条发生共振的可能性,对栅条疲劳进行了计算,并对栅条寿命作出了估算。
This paper introduces the method and results of the vibration study on trash rack of power intake and outlet at Baishan pumped storage hydropower project. By measuring the frequency of the exciting force on trash rack and the free vibration frequency of the trash rack structure, possible resonance occurrence can be judged, metal fatigue strength and lifetime of trash rack can be calculated.
