ANALYSIS OF NOISE SOURCE FOR THE PART VENTILATING FEN(JBT52-2)

本文对JBT52-2型局扇噪声源建立声学模型并对其产生的噪声进行了动态测试和数据处理,找出了噪声源,为控制JBT52-2型局扇噪声指明了明确的方向和可靠的依据。

The paper established acoustic model of noise source for the part ventilating fen (JBT52-2), carried out trend measuring and data processing of noise, and sought for the noise source. For con- trolling noise of the part ventilating fen, paper showed clearing way and reliable data.
