The Establishment and Analysis of the Radiation Noise Model of the Ventilator Enclosure

Article Preview

Abstract:

The radiation noise of the ventilator enclosure is mainly caused by the vibration of the enclosure. It is not easy to calculate and measure. By analyzing the reasons for the radiation noise of the ventilator enclosure, this paper establishes the noise model, uses a series of numerical processing techniques, and overcomes the past complexity and diversity of the numerical solution. By means of the model verification, the comparison between the numerical solution and the measured value shows that this method can be used to calculate some complex noise power.
