| Abstract: | The steel chimney self-vibration frequencies are calculated by FEM and measured on site. The vibration of steel chimney is studied from the aspects of chimney self-vibration frequencies, wind Vibration frequencies and Reynolds number. The resonance domain and causes of the chimney with wind are found out. The measures to solve the problem of the chimney swing are presented. |
