| Abstract: | Preliminary calculation and test confirmation have been carried out for the first six orders of volute self-vibration frequency of T9-19No.4A centrifugal fan.The forced vibration of the fan volute and the noise caused by the volute vibration have been measured and analyzed under the different operating conditions.The study work can be for reference for the noise reduction of small centrifugal fans with forward-swept blades. |
