摘　　要：本文采用有限元和简化方法计算了烟囱自振频率,从烟囱的自振频率、风振动频率、雷诺数三方面研究了该烟囱的振动问题,分析了振动的原因,并提出了相应的解决办法。In this paper, the chimney frequencies were calculated by two methods, such as FEM and simplified method. The vibration of a steel chimney is studied form the aspects of chimney frequencies, wind vibration frequencies and Reynolds, and the resonance of its vibration is analysed. At last, the measures to mitigate the vibration of the steel chimney are presented and the swing of the chimney is sloved.
