摘要(Abstract):

评估和分析了某一型号的一类轴流通风机内部几种空气动力噪声源产生的噪声特性,绘制了各种噪声源的频谱特性区间,对各种噪声源产生的噪声声压级进行了迭加,给出了迭加曲线,并分析了电动机噪声带来的影响。
The performance of several serodynamic noise in one given kind of axial flow fans has evaluated. The frequence spectrum of all the given dynamic noise has been drawn.In the sa me time, according to the method of interative addition about sound pressure level, the curves of the added noise pressure level as the increase of the air flow rate in axial flow fans has been given, and the affect of the electric motor noise has been considered.
