摘要
根据风扇的噪声特性,对风扇噪声进行了分析,并对实机运转情况下的风扇噪声分离方法进行了推算。针对风扇噪声的主要影响因素,对不同直径、不同倾角以及不同扇叶宽度的风扇进行了实机噪声对比分析,说明了设计和使用风扇需要考虑的因素。
According to characteristic of fan noise, an analysis and separation process was adopted in this paper. Some different fans. with different diameter, obliquity, width were tested on engine. The results show that the fan noise must be considered in real usage.
